Diagnostic Accuracy Study of the Pediatric-Specific Ultrasound Scoring System for the Knee Joint in Children With Juvenile Idiopathic Arthritis.

We undertook this study to validate the Pediatric Arthritis Ultrasound Scoring System for the knee joint (PAUSS-knee) in children with juvenile idiopathic arthritis (JIA). Children with JIA were enrolled to prospectively receive a musculoskeletal ultrasound (MSUS) examination of the knee and a physical examination to determine presence/absence of clinical arthritis. MSUS images were scored using the PAUSS-knee, a semiquantitative MSUS scoring system (0-3, normal to severe) for B-mode and power Doppler mode. In addition to MSUS, a subset of participants also received magnetic resonance imaging (MRI) of the knee, which was scored according to the combined Juvenile Arthritis MRI Scoring (JAMRIS) system. Spearman's correlations (rs ) were used to calculate associations between variables. Test characteristics of the PAUSS-knee were calculated with MRI as the reference standard. Inflammatory biomarkers were assessed in synovial fluid from involved knees. Eighty children with JIA contributed 112 MSUSs and 25 MRIs of the knee. Of the knees, 41% (n=46) had clinical evidence of arthritis. The B-mode PAUSS-knee score moderately correlated with clinically determined arthritis (rs = 0.54, P < 0.001) and strongly correlated with the JAMRIS score (rs = 0.75, P < 0.001). Compared with MRI, the area under the curve for the B-mode PAUSS-knee was 0.92. For a cutoff of >1, the B-mode PAUSS-knee had a sensitivity of 83% and specificity of 82%. Biomarker analysis indicates that interleukin-2R levels correlate with PAUSS score. Our data indicate that the PAUSS-knee has excellent accuracy for the diagnosis of arthritis when compared with MRI. The PAUSS-knee has the potential to effectively inform JIA medical decision-making in real time.

The Novel OMERACT Ultrasound Scoring System for Salivary Gland Changes in Patients With Sjögren Syndrome Is Associated With MRI and Salivary Flow Rates.

To assess the construct validity of the novel Outcome Measures in Rheumatology (OMERACT) ultrasound (US) semiquantitative scoring system for morphological lesions in major salivary glands by comparing it with magnetic resonance imaging (MRI) and unstimulated whole salivary flow rates (U-WSFRs) in patients with primary Sjögren syndrome (pSS). Nine sonographers applied the OMERACT 0-3 grayscale scoring system for parotid (PGs) and submandibular glands (SMGs) in 11 patients with pSS who also had MRIs performed. These were evaluated by 2 radiologists using a semiquantitative 0-3 scoring system for morphological lesions. The agreement between US and MRI and the association between U-WSFRs and imaging structural lesions was determined. A score ≥ 2 for both US and MRI was defined as gland pathology. The prevalence of US morphological lesions in 11 patients with a score ≥ 2 was 58% for PGs and 76% for SMGs, and 46% and 41% for PGs and SMGs, respectively, for MRI. The agreement between OMERACT US scores and MRI scores was 73-91% (median 82%) in the right PG and 73-91% (median 91%) in the left PG, 55-91% (median 55%) in the right SMG and 55-82% (median 55%) in the left SMG. When relations between the presence of hyposalivation and an US score ≥ 2 were examined, agreement was 91-100% (median 83%) in both PGs and 55-91% (median 67%) in both SMGs. There is moderate to strong agreement between the OMERACT US and MRI scores for major salivary glands in patients with pSS. Similar agreement ratios were observed between the higher OMERACT US scores and presence of hyposalivation.

Comparison of lung ultrasound scoring systems for the prognosis of COVID-19 in the emergency department: An international prospective cohort study.

The purpose of this study was to evaluate whether the lung ultrasound (LUS) scores applied to an international cohort of patients presenting to the emergency department (ED) with suspected COVID-19, and subsequently admitted with proven disease, could prognosticate clinical outcomes. This was an international, multicentre, prospective, observational cohort study of patients who received LUS and were followed for the composite primary outcome of intubation, intensive care unit (ICU) admission or death. LUS scores were later applied including two 12-zone protocols ('de Alencar score' and 'CLUE score'), a 12-zone protocol with lung and pleural findings ('Ji score') and an 11-zone protocol ('Tung-Chen score'). The primary analysis comprised logistic regression modelling of the composite primary outcome, with the LUS scores analysed individually as predictor variables. Between April 2020 to April 2022, 129 patients with COVID-19 had LUS performed according to the protocol and 24 (18.6%) met the composite primary endpoint. No association was seen between the LUS score and the composite primary end point for the de Alencar score [odds ratio (OR) = 1.04; 95% confidence interval (CI): 0.97-1.11; P = 0.29], the CLUE score (OR = 1.03; 95% CI: 0.96-1.10; P = 0.40), the Ji score (OR = 1.02; 95% CI: 0.97-1.07; P = 0.40) or the Tung-Chen score (OR = 1.02; 95% CI: 0.97-1.08). Compared to these earlier studies performed at the start of the pandemic, the negative outcome of our study could reflect the changing scenario of the COVID-19 pandemic, including patient, disease, and system factors. The analysis suggests that the study may have been underpowered to detect a weaker association between a LUS score and the primary outcome. In an international cohort of adult patients presenting to the ED with suspected COVID-19 disease who had LUS performed and were subsequently admitted to hospital, LUS severity scores did not prognosticate the need for invasive ventilation, ICU admission or death.

The Role of Ultrasound Semi-Quantitative Scoring in the Diagnosis and Assessment of Gout and Hyperuricemia.

To develop an ultrasound semi-quantitative scoring system for the diagnosis and evaluation of gout and hyperuricemia. This study included 348 male patients: 81 patients with asymptomatic hyperuricemia, 182 patients with gout, and 85 patients with other arthritis. Clinical data were collected, ultrasound was detected, gout activity score was calculated to assess disease activity, and statistical analysis was performed. Monosodium urate crystal deposition and subclinical arthritis were detected in 17 patients with asymptomatic hyperuricemia, with lesions concentrated in the metatarsophalangeal joint, ankle and peroneus-longus and brevis at rate of 91.8%. Gout was significantly higher than non-gouty arthritis in crystal scores (sum scores of double contour, aggregates, and tophi), but not in inflammation scores (sum scores of synovial hypertrophy, power Doppler [PD] activity, and tenosynovitis) and bone erosion. The optimal cut-off score for the diagnosis of gout by the crystal score was 2. The sensitivity, specificity, and AUC were 95.4%, 97.1%, and .965, respectively. Gout flare had higher inflammation scores than intercritical gout, while bone erosion scores were lower than intercritical gout. The active gout patients had higher ultrasound scores of tophi, bone erosion, and PD activity than the remission group (P < .001). The sensitivity, specificity and area under the receiver operating characteristic curve (AUC) for the identification with high disease activity gout by ultrasound semi-quantitative composite score were 76.2%, 84.2%, and .812, respectively. Ultrasound helps early identification of patients at risk in asymptomatic hyperuricemia. Ultrasound semi-quantitative scoring allows for more objective and accurate assessment of gout lesions, correlates with disease activity, and helps in the diagnosis and assessment of gout.

HokUS-10 scoring system predicts the treatment outcome for sinusoidal obstruction syndrome after allogeneic hematopoietic stem cell transplantation

Hepatic sinusoidal obstruction syndrome (SOS) is a severe and life-threatening complication after allogeneic hematopoietic stem cell transplantation (HSCT). We conducted a multi-center retrospective study to evaluate the utility of our ultrasonographic scoring system for the diagnosis of SOS (HokUS-10) in predicting SOS-related mortality (SOS-RM). We analyzed a total of 42 patients who developed SOS after HSCT. The cumulative incidences of SOS-RM, non-relapse mortality (NRM), and overall survival at day 180 after the diagnosis of SOS were 26.4%, 28.8% and 54.5%, respectively. The area under the receiver operating characteristic curve analysis showed that the optimal cut-off value of HokUS-10 total score to predict SOS-RM was 8 points after the treatment of SOS. In the individual HokUS-10 score, ascites and portal vein flow-related scores (PV mean velocity and PV flow direction) after the treatment of SOS were shown as significant risk factors for SOS-RM. Our study suggested that US findings after the treatment can predict the treatment outcomes for SOS.

THU677 Performance Of American Thyroid Association And American College Of Radiology Scoring Systems In The Evaluation Of Pediatric Thyroid Nodules

Abstract Disclosure: L. Garabet Diramerian: None. M. Douek: None. G. Tse: None. P. Iskander: None. S. Li: None. M.W. Yeh: None. M.J. Livhits: None. A.M. Leung: None. H.K. Chiu: None. J.X. Wu: None. Background: The underlying malignancy rate of thyroid nodules is higher in pediatric patients compared to adults. Ultrasound scoring systems developed for adult thyroid nodules may not be applicable to pediatric populations. Objective: To evaluate the performance characteristics of adult American Thyroid Association (ATA) and American College of Radiology Thyroid Imaging and Reporting Data System (TIRADS) scoring systems in risk-stratifying pediatric thyroid nodules. Methods: This was a retrospective chart review of pediatric patients aged ≤18 years with thyroid nodules at UCLA Health from 2002-2022. Patients with no available ultrasound images or cytopathology results (fine needle aspiration [FNA] or surgical pathology) were excluded. Each thyroid nodule was scored according to the ATA and TIRADS systems through independent, blinded review by two study radiologists; discordances were arbitrated by a third. For patients who did not undergo thyroid surgery, we considered thyroid nodules benign if their size was stable on repeat ultrasound or if a repeat FNA was benign. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for each system. Sensitivity analyses were performed to determine the optimal size cut-off to recommend FNA biopsy while maintaining a sensitivity equivalent to that of adults. Results: There were 77 patients (median age, 15 years [range 2-18]); 71.4% female) with 115 thyroid nodules. The underlying malignancy rate was 27.8%. Using adult-size cut-offs for FNA biopsy, the ATA scoring system would have failed to recommend biopsy for 11 of 32 malignant nodules, and had the following performance: sensitivity 66%, specificity 55%, NPV 81%, and PPV 36%. The TIRADS scoring system would have failed to recommend biopsy for 15 of 32 malignant nodules and had the following performance: sensitivity 53%, specificity 87%, NPV 83%, and PPV 61%. In sensitivity analyses, the optimal size cut-offs for FNA using the ATA scoring system were: 2 cm for very low risk, 1 cm for low risk, and 0.5 cm for intermediate and high risk categories (sensitivity 94%; specificity 33%). The optimal size cut-offs for FNA using TIRADS were: 3 cm for TIRADS-2, 0.8 cm for TIRADS-3 and TIRADS-4, and 0.5 cm for TIRADS-5 (sensitivity 91%; specificity 59%). Conclusion: The adult ATA and TIRADS ultrasound scoring systems have low sensitivity for thyroid cancer in pediatric thyroid nodules. Lowering the size cutoffs for recommending thyroid FNA biopsy increases sensitivity to &amp;gt;90% for both ATA and ACR TIRADS scoring systems. Presentation: Thursday, June 15, 2023

Pediatric Ultrasound Appendicitis Score for the Diagnosis of Acute Appendicitis to Reduce Computed Tomography Scan Utilization.

Acute appendicitis is one of the most common reasons for pediatric surgical consultation in the emergency room. Although acute appendicitis is a clinical diagnosis, the use of imaging in the emergency department to assist with the diagnosis is very common. Ultrasound is frequently utilized in pediatrics because of the radiation risks associated with computed tomography (CT) scan. The risks of radiation in the pediatric population are much more significant than in adults. Reasons for this include smaller size so there is a relative higher radiation dose than for larger adults, radiosensitive organs such as thyroid, bone marrow, and gonads, and radiation exposure earlier in life allows for more time that a radiation induced cancer could develop. The risks of radiation from imaging are increased with cumulative dosing. The purpose of this study was to incorporate the pediatric appendicitis score (PAS) and standardized ultrasound scoring system to provide a combined score that would assist with the clinical diagnosis of acute appendicitis and avoid the need for a CT scan. The presented data shows that for scores of 7 or more, the specificity and sensitivity is 90% and 90.2%, respectively for the diagnosis of acute appendicitis. This study validates the combined score, shows the specific cutoffs, and initiates the discussion that CT scan may not always be required for diagnosing acute appendicitis if this scoring system is used.

Ultrasound scoring system for prenatal diagnosis of placenta accreta spectrum

BackgroundTo develop an ultrasound scoring system for placenta accreta spectrum (PAS), evaluate its diagnostic value, and provide a practical approach to prenatal diagnosis of PAS.MethodsA total of 532 pregnant women (n = 184 no PAS, n = 120 placenta accreta, n = 189 placenta increta, n = 39 placenta percreta) at high-risk for placenta accreta who delivered in the Third Affiliated Hospital of Zhengzhou University between January 2021 and December 2022 underwent prenatal ultrasound to evaluate placental invasion. An ultrasound scoring system that included placental and cervical morphology and history of cesarean section was created. Each feature was assigned a score of 0 ~ 2, according to severity. Thresholds for the total ultrasound score that discriminated between no PAS, placenta accreta, placenta increta, and placenta percreta were calculated.ResultsUnivariate and multivariate regression analysis identified seven indicators of PAS that were included in the ultrasound scoring system, including placental location, placental thickness, presence/absence of the retroplacental space, thickness of the retroplacental myometrium, presence/absence of placental lacunae, retroplacental myometrial blood flow and history of cesarean section. Using the final ultrasound scoring system, no PAS is diagnosed at a total score < 5, placenta accreta or placenta increta is diagnosed at a total score 5–10, and placenta percreta is diagnosed at a total score ≥ 10.ConclusionsThis study identified seven indicators of PAS and included them in an ultrasound scoring system that has good diagnostic efficacy and clinical utility.Trial registrationChiCTR2300069261 (retrospectively registered on 10/03/2023).

Ultrasonographic appearance of supraspinatus and biceps tendinopathy improves in dogs treated with low-intensity extracorporeal shock wave therapy: a retrospective study.

This study aimed to determine whether dogs with shoulder tendinopathy diagnosed via musculoskeletal ultrasound would show improvement in imaging after treatment using piezoelectric shockwave therapy and rest. Medical records were reviewed for dogs diagnosed with biceps and/or supraspinatus tendinopathy via musculoskeletal ultrasound, treated using piezowave shockwave, and re-imaged post-treatment. Data collected included patient signalment, duration and grade of lameness, prior rest, piezowave dose, and patient outcome, including a return to sport where applicable. Images were scored using an adapted ultrasound grading scale, in addition to obtaining cross-sectional area measurements. Statistics included Shapiro-Wilk tests (normality), Wilcoxon matched pairs signed rank tests (pre- vs. post-treatment comparisons), and Spearman's correlation coefficients (lameness grade vs. ultrasound score) (significant at P < 0.05). In total, 26 of 30 dogs had pathology involving both the biceps and supraspinatus tendons in one limb, with 27 of 30 having tendon/s affected bilaterally. For both tendons, post-treatment cross-sectional area and ultrasound score were significantly lower than pre-treatment (P < 0.001). Lameness decreased clinically (P < 0.0001) following piezowave shockwave treatment regardless of the tendons involved, but the lameness score did not correlate with the ultrasound score for either tendon. Dogs with tendinopathy of the biceps brachii and supraspinatus showed significant improvement on follow-up musculoskeletal ultrasound and lameness evaluation after the treatment of their tendons using piezoelectric shockwave therapy with rest. Canine biceps brachii and supraspinatus tendinopathy can cause variable lameness and ultrasonographic appearance, which improves after shockwave therapy and rest. The ultrasound scoring system and cross-sectional area assessment provide useful outcome measures for clinical cases.

Development and validation of an OMERACT ultrasound scoring system for the extent of calcium pyrophosphate crystal deposition at the joint level and patient level.

The Calcium Pyrophosphate Deposition (CPPD) subgroup of the Outcome Measures in Rheumatology (OMERACT) Ultrasound working group was established to validate ultrasound as an outcome measure instrument for CPPD, and in 2017 has developed and validated standardised definitions for elementary lesions for the detection of calcium pyrophosphate crystals in joints. The aim of this study was to develop and evaluate the reliability of a consensus-based ultrasound scoring system for CPPD extent, representing the next phase in the OMERACT methodology. In this study the novel scoring system for CPPD was developed through a stepwise process, following an established OMERACT ultrasound methodology. Following a previous systematic review to gather available evidence on existing scoring systems for CPPD, the novel scoring system was developed through a Delphi survey based on the expert opinion of the members of the OMERACT Ultrasound working group-CPPD subgroup. The reliability of the scoring system was then tested on a web-based and patient-based exercise. Intra-reader and inter-reader reliability of the new scoring system was assessed using weighted Light's κ coefficients. The four-grade semiquantitative scoring system consisted of: grade 0 (no findings consistent with CPPD), grade 1 (≤3 single spots or 1 small deposit), grade 2 (>3 single spots or >1 small deposit or ≥1 larger deposit occupying ≤50% of the structure under examination in the reference image-ie, the scanning view with the highest grade of depositions), and grade 3 (deposits that occupy more than 50% of the structure under examination in the reference image). The score should be applied to the knee (menisci and hyaline cartilage) and the triangular fibrocartilage complex of the wrist. The intra-reader and inter-reader reliabilities on static images were almost perfect (κ 0·90 [95% CI 0·79-1·00] and κ 0·84 [0·79-0·88]), and on the eight patients recruited (four [50%] female and four [50%] male) were substantial (κ 0·72 [95% CI 0·47 to 0·96] and 0·66 [0·61 to 0·71]). This OMERACT ultrasound scoring system for CPPD was reliable on both static images and patients. The scoring system might be a valuable tool for ensuring valid and comparable results in clinical trials and could help monitor the extent of crystal deposition in patients with CPPD in clinical practice.

A valuable endobronchial ultrasound scoring system predicting malignant lymph nodes.

This study aims to determine the sonographic criteria of lymph nodes to predict malignancy with endobronchial ultrasound. A total of 1,987 lymph nodes of 967 patients (666 males, 301 females; mean age: 62.1±11.9 years; range, 21 to 90 years) between May 2016 and July 2020 were retrospectively analyzed. The endobronchial ultrasound images of lymph nodes were evaluated according to the following criteria: size (short axis >1 cm), shape (round or oval), margin (distinct or indistinct), coagulation necrosis sign (present or absent), central hilar structure (present or absent) and echogenicity (homogeneous or heterogeneous). A scoring system was developed for predicting malignancy. A total of 765 (38.5%) of the lymph nodes were malignant. In the univariate analysis, size >1 cm, round shape, distinct margin, absence of central hilar structure, presence of coagulation necrosis sign, and heterogeneity were significant predictors of malignancy (p<0.001 for all). In the multivariate analysis, the main independent predictors were heterogeneity and presence of coagulation necrosis sign (odds ratio=5.9, 95% confidence interval: 4.2-8.2 vs. odds ratio=3.1 95% confidence interval: 2.2-4.5, respectively). A cut-off value for endobronchial ultrasound score of ≥4 increased the malignancy risk 30 times with a sensitivity of 84.7%, and specificity of 84.5%. Our study results show that endobronchial ultrasound scoring system with six criteria has a high sensitivity and specificity for predicting malignant lymph nodes.

P-480 An endometrial receptivity scoring system evaluated by ultrasonography in patients undergoing frozen-thawed embryo transfer: a prospective cohort study

Abstract Study question Can a scoring system based on ultrasound indicators evaluate the endometrial receptivity (ER) in a noninvasive and effective manner? Summary answer A noninvasive ultrasound scoring system was proposed, through which, a patient’s ER situation can be assessed in a noninvasive, efficient and accurate manner. What is known already Endometrial receptivity (ER) refers to the receptiveness of the endometrium to embryonic implantation and subsequent development. The endometrium plays a crucial role in embryo implantation, especially when the embryo quality is good. Ultrasound technology has become a routine method for ER evaluation. The independent evaluation value of various ultrasonic indicators is controversial. Some researchers designed a multi-index prediction system, but the prediction results vary. To further understand ER, we performed this prospective cohort study to help evaluate ER in a noninvasive and efficient manner. Study design, size, duration This prospective study included 197 infertile women undergoing FET from April 2019 to July 2021. Transvaginal three-dimensional ultrasound was performed on the transfer day to evaluate ER, including endometrial thickness, morphology, volume, movement, blood flow and flow index. Participants/materials, setting, methods This study was conducted at the Reproductive and Genetic Hospital of CITIC-Xiangya. The primary outcome of this study was the clinical pregnancy rate. All included patients were divided into a pregnant group and a nonpregnant group according to whether clinical pregnancy was achieved. Main results and the role of chance A total of 197 FET patients with 139 pregnancies (70.5%) were analysed. Primary infertility (adjusted odds ratio (aOR), 1.98; 95% confidence interval (CI), 1.01–3.882; P = 0.047) and more frequent endometrial peristalsis (aOR, 1.33; 95% CI, 1.028–1.722; P = 0.03) were protective factors against clinical pregnancy. Scores of 1 to 2 were given according to the relationship between different groups of ultrasonic indices and the clinical pregnancy rate (CPR). A patient’s ER score was the sum of the scores of the 6 items. The ER score was significantly higher in the pregnant group than that in the nonpregnant group (7.40 ± 1.73 versus 6.33 ± 1.99, P = 0.001). The CPR increased as the ER score increased; the CPR significantly improved for the group with total ER scores of &amp;lt; 6 to ≥ 6 (45.5% versus 75.6%, P = 0.001). Limitations, reasons for caution First, this study only included natural cycles of FET. The application for other populations remains to be verified. Second, perhaps with the progress of ultrasonic technology, there will be new and more direct indicators. Third, we did not further explore the relationship between ER and the live birth rate. Wider implications of the findings The scoring system provides a broader idea for guiding clinical practice to perform more efficient transplantation and provide a noninvasive evaluation of ER in the future.

Diagnostic performance of the EU TI-RADS and ACR TI-RADS scoring systems in predicting thyroid malignancy.

Several ultrasound scoring systems have been developed to stratify the risk of malignancy of thyroid nodules, including ACR (American College of Radiology) and EU (European) TI-RADS. This study aimed to assess the diagnostic performance of these two classifications using histology as a reference standard. It was a single-centre, retrospective study including 156 patients who underwent thyroidectomy. Ultrasound data of 198 nodules (99 malignant nodules and 99 benign nodules) were analysed. Both classifications were applied for all nodules. Ultrasound criteria associated with malignancy were solid composition (OR=7.81; p < 10-3 ), hypoechoic character (OR=16.42; p < 10-3 ), irregular contours (OR=7.47; p < 10-3 ), taller-than-wide shape (OR=3.58; p = 0.02), microcalcifications (OR=3.02; p = .006) and the presence of cervical adenopathy (OR=3.89; p = .006). The prevalence of malignancy was 15.5%, 69% and 76.9% for EU TI-RADS categories 3, 4 and 5, respectively. It was 33.3%, 57% and 91.1% for ACR TI-RADS categories 3, 4 and 5, respectively. For category 5, EU TI-RADS and ACR TI-RADS had sensitivities of 60% and 41%, specificities of 82% and 96%, respectively. For categories 4 and 5 combined, the diagnostic performance of these two classification systems became comparable with a sensitivity of 89% and 86% for EU-TIRADS and ACR-TIRADS, respectively. The area under the ROC curve was 0.81 for the EU TI-RADS classification and 0.82 for the ACR TI-RADS classification. EU TI-RADS and ACR TI-RADS scoring systems seem to be comparable in predicting malignancy in thyroid nodules.

Development of an Ultrasound Scoring System to Describe Brain Maturation in Preterm Infants.

Cerebral maturation in preterm infants predominantly occurs postnatally, necessitating the development of objective bedside markers to monitor this process. This study aimed to develop a straightforward objective Ultrasound Score of Brain Development to assess cortical development in preterm infants. A total of 344 serial ultrasound examinations from 94 preterm infants born at ≤ 32 weeks of gestation were analyzed to identify brain structures suitable for a scoring system. Among 11 candidate structures, 3 cerebral landmarks were selected due to their correlation with gestational age: the interopercular opening (P < .001), the height of the insular cortex (P < .001), and the depth of the cingulate sulcus (P < .001). These structures can be easily visualized in a single midcoronal view in the plane through the third ventricle and the foramina of Monro. A score point from 0 to 2 was assigned to each measurement, culminating in a total score ranging from 0 to 6. The Ultrasound Score of Brain Development correlated significantly with gestational age (P < .001). The proposed Ultrasound Score of Brain Development has the potential for application as an objective indicator of brain maturation in correlation with gestational age, circumventing the need to rely on individual growth trajectories and percentiles for each specific structure.

Comparative Study of the Efficacy of the Ovarian-Adnexa Reporting and Data System Ultrasound Combined With Contrast-Enhanced Ultrasound and the ADNEX MR Scoring System in the Diagnosis of Adnexal Masses

The aims of this study were to develop the Ovarian-Adnexa Reporting and Data System (O-RADS) and O-RADS+contrast-enhanced ultrasound (O-RADS CEUS) scoring system to distinguish adnexal masses (AMs) and to compare the diagnostic efficacy of these systems with that of a magnetic resonance imaging scoring system (ADNEX MR). We retrospectively evaluated 278 ovarian masses from 240 patients between May 2017 and July 2022. Pathology and adequate follow-up were used as reference standards for comparing the validity of O-RADS, O-RADS CEUS and ADNEX MR scoring to diagnose AMs. Area under the curve (AUC), sensitivity and specificity were calculated. The inter-class correlation coefficient (ICC) was calculated to evaluate inter-reader agreement (IRA) between the two sonographers and two radiologists who analyzed the findings with the three modalities. The AUCs of O-RADS, O-RADS CEUS and ADNEX MR scores were 0.928 (95% confidence interval [CI]: 0.895-0.956), 0.951(95% CI: 0.919-0.973) and 0.964 (95% CI: 0.935-0.983), respectively. Their sensitivities were 95.7%, 94.3 and 91.4%, and their specificities were 81.3%, 92.3% and 97.1%, respectively. The three modalities had accuracies of 84.9%, 92.8% and 95.7%, respectively. O-RADS had the highest sensitivity but significantly lower specificity (p < 0.001), whereas the ADNEX MR scoring had the highest specificity (p < 0.001) but lower sensitivity (p < 0.001). O-RADS CEUS had intermediate sensitivity and specificity (p < 0.001). The addition of CEUS significantly improves the efficacy of O-RADS in diagnosing AMs. The diagnostic efficacy of the combination is comparable to that of the ADNEX MR scoring system.

Lung Ultrasound to Determine the Effect of Lower vs. Higher PEEP on Lung Aeration in Patients without ARDS—A Substudy of a Randomized Clinical Trial

Background: Ventilation with lower positive end–expiratory pressure (PEEP) may cause loss of lung aeration in critically ill invasively ventilated patients. This study investigated whether a systematic lung ultrasound (LUS) scoring system can detect such changes in lung aeration in a study comparing lower versus higher PEEP in invasively ventilated patients without acute respiratory distress syndrome (ARDS). Methods: Single center substudy of a national, multicenter, randomized clinical trial comparing lower versus higher PEEP ventilation strategy. Fifty–seven patients underwent a systematic 12–region LUS examination within 12 h and between 24 to 48 h after start of invasive ventilation, according to randomization. The primary endpoint was a change in the global LUS aeration score, where a higher value indicates a greater impairment in lung aeration. Results: Thirty–three and twenty–four patients received ventilation with lower PEEP (median PEEP 1 (0–5) cm H2O) or higher PEEP (median PEEP 8 (8–8) cm H2O), respectively. Median global LUS aeration scores within 12 h and between 24 and 48 h were 8 (4 to 14) and 9 (4 to 12) (difference 1 (–2 to 3)) in the lower PEEP group, and 7 (2–11) and 6 (1–12) (difference 0 (–2 to 3)) in the higher PEEP group. Neither differences in changes over time nor differences in absolute scores reached statistical significance. Conclusions: In this substudy of a randomized clinical trial comparing lower PEEP versus higher PEEP in patients without ARDS, LUS was unable to detect changes in lung aeration.

A scoring diagnostic system based on biparametric ultrasound features for prostate cancer risk assessment.

Ultrasound has advantages in prostate cancer (PCa) detection and biopsy guidance but lacks a comprehensive quantitative evaluation model with multiparametric features. We aimed to construct a biparametric ultrasound (BU) scoring system for PCa risk assessment and to provide an option for clinically significant prostate cancer (csPCa) detection. From January 2015 to December 2020, 392 consecutive patients at Chongqing University Cancer Hospital who underwent BU (grayscale, Doppler flow imaging, and contrast-enhanced ultrasound) and multiparametric magnetic resonance imaging (mpMRI) before biopsy were retrospectively enrolled in the training set to construct the scoring system. From January 2021 to May 2022, 166 consecutive patients at Chongqing University Cancer Hospital were retrospectively enrolled in the validation set. The ultrasound system was compared with mpMRI, and the gold standard was a biopsy. The primary outcome was the detection of csPCa in any area with a Gleason score (GS) ≥3+4, and the secondary outcome was defined as a GS ≥4+3 and/or maximum cancer core length (MCCL) ≥6 mm. Malignant association features in the nonenhanced biparametric ultrasound (NEBU) scoring system included echogenicity, capsule, and gland asymmetrical vascularity. In the biparametric ultrasound scoring system (BUS), the feature of contrast agent arrival time was added. In the training set, the area under the curves (AUCs) of the NEBU scoring system, BUS, and mpMRI were 0.86 [95% confidence interval (CI): 0.82-0.90], 0.86 (95% CI: 0.82-0.90), and 0.86 (95% CI: 0.83-0.90), respectively (P>0.05). Similar results were also observed in the validation set, in which the areas under the curves were 0.89 (95% CI: 0.84-0.94), 0.90 (95% CI: 0.85-0.95), and 0.88 (95% CI: 0.82-0.94), respectively (P>0.05). We constructed a BUS that showed efficacy and value for csPCa diagnosis as compared with mpMRI. However, in limited circumstances, the NEBU scoring system may also be an option.

Development of an ultrasound set for early diagnosis of rheumatoid arthritis: First steps

Introduction/ObjectiveEarly diagnosis of rheumatoid arthritis (RA) can improve the prognosis of the disease by reducing joint destruction and achieving a better rate of remission. Musculoskeletal ultrasound (US) has become a potent tool to detect synovitis and erosions. However, until now, there has been a lack of consensus on the US scoring system to help in diagnosing RA early. The purpose of our study was to elaborate a US set suitable for classifying RA patients with inflammatory arthralgia or expressing synovitis and who did not satisfy ACR/EULAR criteria, called “USSRA” (UltraSound Set for Rheumatoid Arthritis). Materials and methodsA multistep study was conducted. A preliminary set of joints, tendons, and erosions to include in the USSRA were identified through a deep literature screening. The final step of this study was the validation of the final set by international experts in US using a Delphi process. ResultsThe preliminary set included 20 joints, 16 tendons, and 8 erosion sites for assessment. After the Delphi process, the changes were to add an assessment of two additional wrist joints and remove one. As for the tendons, two sites were removed from the final set. No changes were proposed for the section erosions. The elementary lesions and scoring system were clarified. The final USSRA forms include 18 joints, 12 tendons, and 8 sites of erosion. ConclusionThe USSRA is a novel diagnostic tool proposed for detecting early RA in routine practice. The next step will be to assess the reliability of this set in a patient-based exercise.

General anesthesia does not induce ultrasonographic changes in the pleura of healthy adult horses anesthetized for elective magnetic resonance imaging.

To compare thoracic ultrasonographic findings in healthy horses before and after general anesthesia for elective MRI utilizing a recently developed ultrasonographic scoring system to aid clinicians in the early identification of pneumonia following anesthesia. 13 adult horses > 3 years of age. Prior to anesthesia, horses underwent a thorough physical examination, CBC, thoracic radiography, and thoracic ultrasonography. Horses were then anesthetized for elective MRI, and thoracic ultrasonography was repeated within 3 hours after recovery. Thoracic ultrasonographic findings were scored utilizing a recently developed scoring system, and scores were compared before and after anesthesia. There was no significant difference identified in total thoracic ultrasonography score before and after anesthesia, and there was no correlation between thoracic ultrasonography score following anesthesia and the body weight of the horse, the time recumbent, and the dependent side. In healthy horses undergoing anesthesia for elective imaging, there was no significant change in thoracic ultrasonographic findings 3 hours after recovery from anesthesia. These data can aid clinicians in determining the clinical significance of ultrasonographic changes in the lung in the immediate postanesthetic period.

The sensitivity of TIRADS scoring on ultrasonography in the management of thyroid nodules.

To determine the sensitivity of ACR-TIRADS scoring by comparing its results with those obtained on biopsy of respective specimens. This prospective study including N=205 patients with thyroid nodules was conducted in ENT Department of MTI Hayatabad Medical complex, Peshawar during the period from May 1, 2019 to April 30, 2022. Preoperative ultrasonography with assigning of TIRADS scores was performed in all patients. Appropriate thyroidectomies were performed in these patients and specimen biopsied. Pre-op TIRADS scores were compared with biopsy results. To determine the sensitivity of TIRADS, TR1 and TR2 were considered 'benign' and TR3, TR4, TR5 were considered 'malignant' for comparison with biopsy results. The mean age of patients was 37.68 years with standard deviation of ±11.52. The M: F ratio was 1:3.5. Nineteen patients (9.27%) had solitary thyroid nodules & 186 (90.73%) had multinodular goiters. TIRADS scoring was benign for 171 (83.41%) and malignant for 34 (16.58%) nodules. The biopsy results revealed 180 (87.80%) nodules to benign and the rest as malignant. The sensitivity, specificity and diagnostic accuracy were calculated at 80%, 92.77% and 91.21% respectively. Chi square test and p-value determination showed that there was a strong positive concordance between TIRADS scores & biopsy results which is highly significant (p=.001). The Ultrasonographic ACR-TIRADS scoring and risk stratification system is highly sensitive for detecting malignancy in thyroid nodules. It is, therefore, a reliable technique in the initial assessment of thyroid nodules and decisions can safely be based on its results. In cases of doubt, clinical judgment should be exercised before making final decision.
