Potential diagnostic application of a novel deep learning- based approach for COVID-19

COVID-19 is a highly communicable respiratory illness caused by the novel coronavirus SARS-CoV-2, which has had a significant impact on global public health and the economy. Detecting COVID-19 patients during a pandemic with limited medical facilities can be challenging, resulting in errors and further complications. Therefore, this study aims to develop deep learning models to facilitate automated diagnosis of COVID-19 from CT scan records of patients. The study also introduced COVID-MAH-CT, a new dataset that contains 4442 CT scan images from 133 COVID-19 patients, as well as 133 CT scan 3D volumes. We proposed and evaluated six different transfer learning models for slide-level analysis that are responsible for detecting COVID-19 in multi-slice spiral CT. Additionally, multi-head attention squeeze and excitation residual (MASERes) neural network, a novel 3D deep model was developed for patient-level analysis, which analyzes all the CT slides of a given patient as a whole and can accurately diagnose COVID-19. The codes and dataset developed in this study are available at https://github.com/alrzsdgh/COVID. The proposed transfer learning models for slide-level analysis were able to detect COVID-19 CT slides with an accuracy of more than 99%, while MASERes was able to detect COVID-19 patients from 3D CT volumes with an accuracy of 100%. These achievements demonstrate that the proposed models in this study can be useful for automatically detecting COVID-19 in both slide-level and patient-level from patients’ CT scan records, and can be applied for real-world utilization, particularly in diagnosing COVID-19 cases in areas with limited medical facilities.

Incidence and predictors of permanent pacemaker implantation after transcatheter aortic valve implantation with a balloon-expandable biosprosthesis in patients with bicuspid aortic valves.

There are few data on permanent pacemaker implantation (PPMI) in patients who have undergone transcatheter aortic valve implantation (TAVI) for bicuspid aortic valve (BAV) stenosis. The purpose of this study was to evaluate the predictors and incidence of PPMI in bicuspid patients using a balloon-expandable (BE) TAVI device. A total of 62 patients with bicuspid morphology who had undergone successful TAVI using a BE device without previous PPMI were included (retrospectively). Their baseline clinical, electrocardiographic (ECG), echocardiographic, and multislice computed tomography (MSCT) details were collected. The incidence of PPMI after TAVI in this BAV cohort was 12.9%. All eight patients with PPMs were found to have type 1 left-right (L-R) fusion morphology. In univariate analysis, the presence of right bundle branch block (RBBB) in preprocedural ECG (p < 0.0001), short membranous septum (MS) evaluated in MSCT (p < 0.0001), and increased annulus-left main coronary artery distance (p = 0.02) were statistically significant for PPMI. Among these parameters included in the model using multivariate Firth logistic regression analysis, the presence of preprocedural RBBB (p = 0.001) and shortness of the MS in MSCT (p = 0.004) were independent risk factors for predicting postprocedural PPMI in patients who underwent TAVI among those with BAV. Preprocedural RBBB on ECG and shorter MS are independent risk factors for PPMI after TAVI in BAV patients and these parameters should be considered before the procedure to guide clinical decision making. Type 1 L-R patients may be considered at increased risk of PPMI.

The role of external iliac artery diameter indexed to BSA score in predicting vascular access complications after transfemoral transcatheter aortic valve implantation.

Aortic stenosis is the most common primary valve disease and requires invasive treatment. Transcatheter aortic valve implantation (TAVI) from a transfemoral access is a routine intervention worldwide. To investigate the correlation between external iliac artery diameter (EIAD) indexed to body surface area (BSA) (EIAD-BSA) and access site complications in patients undergoing TAVI via transfemoral access (TF) (TF-TAVI). Patients underwent TF-TAVI in 2017-2019 at the Upper-Silesian Medical Center in Katowice. Based on the preoperative multi-slice computed tomography (MSCT), pre-specified measurements of the ilio-femoral vessels were performed. The results were indexed to BSA and body mass index (BMI). Complications after TAVI were defined by Valve Academic Research Consortium 3 (VARC-3). The primary outcome regarding the adverse events after TAVI was the composite of access site complications requiring surgical intervention or blood transfusion. The registry included 193 unselected patients with severe symptomatic aortic stenosis. Vascular and access-related complications including bleeding occurred in 17.1% of patients. Major TAVI access site complications (VARC-3) were reported in 5.7% of patients, while minor complications (VARC-3) occurred in 2.6%. EIAD-BSA demonstrated a positive correlation with the access site complications primary endpoint. Patients with greater EIAD-BSA had a numerically higher number of access site adverse events requiring surgical intervention or blood transfusion: n = 12 (5%) vs. n = 4 (4%), p = 0.011. External iliac artery diameter indexed to BSA could be an underestimated indicator of unfavorable outcomes after TF-TAVI, predicting periprocedural access site complications.

Evaluation of Factors Influenced on the Effectiveness of Percutaneous Nephrolithotomy.

Generally, there are many methods for the treatment of urinary stones, of which percutaneous nephrolithotomy (PCNL) is a minimally invasive and highly effective method, and now become the first-line management for urinary stones, especially in the cases of complex stones and staghorne calculi. Accurate assessment of stone location, stone morphology, degree of hydronephrosis as well as urinary system abnormalities is extremely important in the percutaneous nephrolithotomy strategy. The aim of this study was to evaluate the S.T.O.N.E score as well as other factors that influenced the effectiveness of PCNL. Descriptive study on 71 patients with kidney stones, who underwent multi-slice CT scan of the urinary system before PCNL and then PCNL at Hanoi Medical University Hospital from July 2022 to July 2023. All patients received the informed consent and agreed to participate in the study. The factors included the stone area, the track length (from the skin surface to the stone central), the degree of urinary tract dilatation, the number of involved calyces, the density of stone, the renal parenchyma thickness, the ureteral wall thickness and fat infiltration measured on MSCT non-contrast phase. These factors were used to predict the effectiveness of PCNL including the stone clearance rate (SCR) and the operation time. The mean age of the patient group was 53.8±12.3. The male/female ratio was 1.54. There was a significant difference (p<0.05) between the following factors and the operation time: the stone area (<400, 400-799, 800-1599 and >1600 mm2), the degree of urinary tract dilatation (no or might and moderate or severe dilatation), the number of involved calyces (≤ 2, 3 and staghorne calculi), the renal parenchyma thickness (<18 mm and ≥18mm). In contrast, there were no significant differences between the following factors and the surgery time (p>0.05): the track length (<100 and ≥100 mm), and the stone density (<950 and ≥950 HU). Regarding the S.T.O.N.E score (included five factors: Size, Track length, Obstruction, Number of involved calyces, and Evaluation of stone density), there was a strong correlation between S.T.O.N.E score and the surgery time (p<0.001, r=0.94), and the SCR (p=0.001, r=-0.97). The evaluation of these factors played an important role in the prediction of the effectiveness of PCNL.

Treatment of a Patient With Closed Liver Injury Using Interventional Methods:&#x0D; a Case Study

Background. Mechanical injury occupies a leading position among the causes of mortality in the working-age population. Diagnosis and treatment of isolated and combined abdominal traumas accompanied by bleeding appear to be a specific challenge. Due to difficulties in diagnosis and treatment, they are characterized by frequent complications and an increased mortality rate.Currently, there is no uniform tactics for diagnosing and treating patients with liver damage. In Russia and globally, new approaches are being actively introduced for the treatment of patients with closed liver traumas using minimally invasive techniques.The aim of study was to present a clinical case of a patient with a closed liver injury treated using interventional methods, such as angiography and embolization.Materials and methods. According to conventional techniques, the patient had to undergo laparotomy with complex manipulations to stop intra-abdominal bleeding from a ruptured liver, which would inevitably worsen her condition in the context of a presenting severe injury.Multiple studies reported that the number of postoperative complications after laparotomy is up to 41%, and in case of combined trauma 10-35% of complications can be one of the causes of death [6, 7, 8]. In order to avoid more traumatic treatment approaches, we applied tactics using minimally invasive high-tech diagnostic and treatment options.Results. To stop intra-abdominal bleeding from a liver rupture, which was previously diagnosed during multislice computed tomography (MSCT) with intravenous contrast, using interventional options, selective embolization of the segmental branch of the right hepatic artery was performed with an adhesive composition. The post-traumatic period proceeded without complications; in 14 days after the injury, the patient was discharged in satisfactory condition.Conclusion. Minimally invasive and conservative treatment of patients with closed abdominal traumas using interventional radiology can be successfully applied in specialized trauma centers.

Postmortem Computed Tomography: A Supplant Technique to Autopsy for Firearm Injuries in the Head

Background: Autopsy is more time-consuming if the bullet/bullets are lodged at the difficult-to-access sites of the head, especially maxillofacial regions. The procedure of suturing the deceased becomes even more difficult after the retrieval of bullets post-dissection of facial tissues. The altered aesthetics psychologically and emotionally disturb the already bereaved next of kin. The authors explored the utility of PMCT and propose a methodology of targeted dissection/minimally invasive approach to retrieve the bullet. The authors discussed the feasibility to conclude the cause of death in cases of single/multiple firearm injuries to the head using PMCT alone. Methods: The authors evaluated three cases of firearm deaths at a distance lesser than close range to the head. The deceased was subjected to PMCT scanning using a 16-slice Multi-Slice CT spiral scanner and findings were analyzed using the Vitrea software v.6.9.1 with the slice thickness ranging from 0.5mm to 5mm. A routine conventional autopsy was conducted post-scanning. Two of the three cases were suicide and succumbed to a single firearm injury while the third case was a homicide due to multiple firearm injuries. Conclusion: PMCT alone can be utilized and relied upon in deaths due to a single shot to the head and suggests a combined methodology of PMCT evaluation and minimally invasive approach in cases of multiple firearm injuries for better correlation of wound track. Lastly, PMCT helped in a targeted approach to reach the in situ bullets more precisely than any other radiological technique which upholds the humanitarian forensic aspect.

Sclerotherapy with intralesional bleomycin injection under guidance of multi-slice CT for retrobulbar orbital low-flow vascular lesions-single-center experience.

This study investigated the safety and efficacy of sclerotherapy with intralesional bleomycin injection (IBI) for retrobulbar orbital low-flow vascular lesions under multi-slice computed tomography (CT) guidance. Between January 2010 and September 2021, consecutive patients with retrobulbar orbital low-flow vascular lesions who underwent CT-guided IBI at a tertiary centre in Taiwan were enrolled. Their medical records and imaging data were retrospectively collected. This study enrolled 13 patients (7 male and 6 female patients; age range: 1-57 years; mean age: 25.9 years) with lymphatic malformation (LM, n = 4), venolymphatic malformation (n = 1), and venous malformation (VM, n = 8). The overall radiological response rate was 76.9% (10 of 13); the radiological response rate was 75.0% in the VM group (6 of 8) and 75.0% in the LM group (3 of 4). Moreover, 3 patients (23.1%) had minor complications and 1 (7.7%) had a major complication. The mean clinical and radiological follow-up was 8.3 months and no recurrence or progression was reported. CT-guided IBI is an effective and relatively safe minimally invasive treatment for retrobulbar orbital low-flow vascular lesions, with an overall radiological response rate of 76.9% in a mean of 1.5 sessions and a low complication rate. CT-guided sclerotherapy with IBI is a relatively safe, effective, and feasible alternative treatment option for retrobulbar orbital low-flow vascular lesions.

A pregnant lady (G3P2A0) with fetal distress and brain tumor

Intracranial tumors or brain tumors are one of the most feared diseases because the brain is an important central organ. Brain tumors share several pathophysiologic features and may present with a variety of signs and symptom.&#x0D; A 39-year-old female patient, G3P2A0 of 28 weeks gestation complained of frequent throbbing headaches for the last 2 y. On physical examination, she had decreased consciousness, fever and anisocor pupil. Laboratory tests found leukocytosis. Cerebral multi-slice computed tomography (MSCT) found heterodense lesion at intraaxial supratentorial region with irregular border, necrotic components and bleeding in the right basal ganglia to the right temporal lobe. There were signs of fetal distress on cardiotocography (CTG).&#x0D; Management during pregnancy depends on the nature of the tumor. There may be some conflict between maternal and fetal interests in the patient with increased ICP. The patient was diagnosed with brain tumor in the right basal ganglia and undergoing treatment in the ICU. As a 28-week pregnant patient with fetal distress diagnosed with brain tumor, she needed to be observed and periodically evaluated. However, the patient's prognosis was dubia ad malam.&#x0D; Key words: Brain Tumor; Fetal Distress; Pregnancy&#x0D; Citation: Arianto AT, Heryadi MI.

Anesthetic challenges during repairing left pulmonary artery sling without cardiopulmonary bypass: a case report

Left pulmonary artery sling (LPAS) is a rare vascular anomaly. The general surgical technique to correct it is through median sternotomy under cardiopulmonary bypass (CPB). In this case, we discuss the anesthetic management of left pulmonary artery (LPA) reimplantation without CPB to improve the understanding and provide an overview for practitioners in managing patients with this rare vascular anomaly. Patient was a 10 months old baby, with main complaints of shortness of breath since he was 4 months old, and diagnosed with LPAS from cardiac multi-slice CT scan (MSCT) examination. Intraoperatively, when the LPA was clamped, the blood pressure decreased due to decreased preload, and the end-tidal CO2 increased to 70 mmHg due to increased dead space, which was successfully managed. Postoperatively, the patient suffered from ventilator acquired pneumonia (VAP). Evaluating and assessing the potential complications that can occur during the perioperative period will help prepare for management and improve the success of anesthetic management.&#x0D; Abbreviations: CPB- Cardiopulmonary Bypass; ETT- Endotracheal Tube; LPA- Left Pulmonary Artery; LPAS- Left Pulmonary Artery Sling; MSCT- Multi-Slice CT Scan; RPA- Right Pulmonary Artery; VAP- Ventilator Acquired Pneumonia&#x0D; Key words: Left Pulmonary Artery; Anesthesia Management; Pulmonary Sling; Cardiopulmonary Bypass&#x0D; Citation: Arifin A, Perdana A.

Multi-slice CT coronary angiography versus invasive coronary angiography in the assessment of graft patency after coronary artery bypasses graft surgery

BackgroundThe long-term patency of arterial and venous grafts is crucial for the success of CABG. This study was designed to investigate graft patency using 128-slice coronary computed tomography angiography (CCTA) and compared the results with those obtained using invasive coronary angiography (ICA). In this observational cross-sectional study, we included 40 symptomatic post-CABG patients underwent CCTA and ICA within the same month.ResultsFifty-five percent were aged more than 60 years, and 80% were males. 67.5% had diabetes, 90% had hypertension, and 30% were smokers. Mean body mass index was 28.89 ± 5.17 kg/m2. Mean duration since CABG was 5.25 ± 4.04 years. In total, 124 native vessels and 97 grafts were assessed using CCTA and ICA. CCTA delineated 8 non-cannulated venous grafts and 6 non-cannulated left internal mammary artery grafts. CCTA required a significantly lower radiation dose (1165.77 ± 123.54 vs. 47,589.78 ± 6967.53, p < 0.001).ConclusionCCTA can be as accurate as ICA in assessing bypass grafts with less radiation dose, providing a non-invasive reliable tool for evaluation.

Computed tomographic 3D analysis of the cochlear aqueduct—potential and limitations of clinical imaging

Background: The cochlear aqueduct (CA), which connects the scala tympani and the subarachnoid space, and its accompanying structures appear to have a significant relevance during cochlear implantation and an accurate visualization in clinical imaging is of great interest. Aims and Objective: This study aims to determine which potential and limitations clinically available imaging modalities have in the visualization of the CA. Methods: Micro-CT, flat-panel volume computed tomography with and without secondary reconstruction (fpVCT, fpVCTseco) and multislice computed tomography (MSCT) of 10 temporal bone specimen were used for 3D analysis of the CA. Results: FpVCTseco proved superior in visualizing the associated structures and lateral portions of the CA, which merge into the basal turn of the cochlea. All clinical imaging modalities proved equal in analyzing the length, total volume of the CA and its area of the medial orifice. Conclusion: The choice of the most accurate clinical imaging modality to evaluate the CA and its associated structures depends on the clinical or scientific question. Furthermore, this study should provide a basis for further investigations analyzing the CA.

Imaging diagnosis analysis and literature review of intrapulmonary solitary fibrous tumor.

Solitary fibrous tumor (SFT) of the chest mainly arises from the pleura, but intrapulmonary SFT is rare. This study aimed to review and discuss the chest multislice computed tomography (MSCT) and magnetic resonance imaging (MRI) findings of intrapulmonary SFT and summarize existing literature on the disease in order to improve clinicians' understanding and diagnosis of this disease. The imaging findings and clinical data of 4 surgically and pathologically confirmed intrapulmonary SFT cases were retrospectively analyzed in terms of location, morphology, size, density, border, enhancement level of the lesion, and its relationship with surrounding tissue. These findings were combined with a review of 61 cases reported in the literature to characterize the features of intrapulmonary SFT. A total of 65 patients with intrapulmonary SFT were reviewed, consisting of 30 females and 35 males. Of these cases, 21 had a lesion in the left lower lobe, more than in any other part of the lungs. The lesions were clear, had a quasicircular boundary, and were distinctly separated from surrounding tissue. Under plain scan, the 4 cases investigated in this study showed lesions of even density, and enhanced scanning revealed geographic enhancement in 2 cases. Of the 65 cases examined, 56 cases were benign, and the remaining 9 cases were borderline or malignant. The imaging findings of intrapulmonary SFT demonstrated certain features, such as lesions with a clear boundary and even density. Imaging examination is important for the diagnosis and differential diagnosis of this disease.

Multi-slice computed tomographic analysis and identification of remarkable anatomical types of segmental bronchi in bilateral inferior lobes: based on extensive data.

The progress of interventional respiratory medicine necessitates a comprehensive knowledge of the segmental bronchi because of their complexity in branching patterns. Therefore, based on extensive research data, we aimed to examine the anatomical diversity and sex-related variations of the segmental bronchial branching patterns in the bilateral inferior lobes. Following the exclusion and inclusion criteria, a total of 10,000 participants who underwent multi-slice computed tomography (MSCT) scans from September 2019 to December 2021 at Cheeloo College of Medicine, Shandong University were enrolled in this retrospective study. The computed tomography (CT) data were utilized to generate three-dimensional (3D) and virtual bronchoscopy (VB) simulations of a bronchial tree using the syngo.via post-processing workstation. The distinct bronchial patterns in the bilateral inferior lobes were then found and categorized using the reconstructed images. The proportions of different types of bronchial branches and their sex-related correlations were analyzed by cross-tabulation and chi-square analysis. Our findings primarily identified four types of bronchial branching patterns in the right inferior lobe (RIL), i.e., (B6, B7, B8, B9+10), 71.44%; (B6, B7, B8+9, B10), 16.06%; (B6, B7+8, B9+10), 7.40%; (B6, B7, B8+9+10), 5.10%; and four types in the left inferior lobe (LIL), i.e., (B6, B7+8, B9+10), 82.89%; (B6, B7+8, B9, B10), 13.53%; (B6, B7, B8+9, B10), 2.88%; (B6, B7, B8+9+10), 0.70%. Besides various research methods and outcomes, this study has revealed the types of bronchial branches that were not seen in previous studies. In addition, the proportion of bronchial branches in the LIL did not differ significantly between males and females (P>0.05). However, there was a significant difference in the proportion of bronchial branches in the RIL between sexes (P<0.05). The current study has validated the segmental bronchial variations in the bilateral inferior lobes. The diagnosis of symptomatic patients as well as the performance of interventions like bronchoscopies, endotracheal intubation, and lung resections may be significantly influenced by our findings in the clinical setting.

Correlation between Age and Abdominal Diameter for Estimating Size-Specific dose in Pediatric CT examination

This study aims to investigate the correlation between abdominal diameter against the their ages in pediatric Computed Tomography (CT) examination. The retrospective images from 96 patients ranging from 0–16 years scanned by the Siemens Somatom Go Top 128 Multi-slice CT scanner were evaluated. In a total of 46 patients were scanned by tube current modulation (TCM) approach and the remaining 50 patients were examined whitout TCM. The effective diameter (Deff) for every patient was automatically calculated using IndoseCT. The evaluation of the size and age correlation was carried out using a regression approach from AAPM Task Group 204. In addition, size-specific dose estimate (SSDE) was also calculated using IndoseCT. The results shows that the patient’s diameters increase along the increase of ages (R2 &gt; 0.68) with rapid growth in the ages of 0-1 years. It is also found that the increase in the patient’s diameter leds to the decrease of SSDE in the non-TCM protocol, while the trend in the TCM protocol is different. The SSDE had a tendency to increase along with the increase in patient sizes (R2 &lt; 0.40).

Inpatient covid-19-related comorbidities and ct-semiotics

Introduction. In the Russian Federation, registration of individual COVID-19 cases started at the end of January 2020 that markedly increased in the second half of March. At the moment, the situation with COVID-19 is unstable. As of 2023, COVID-19 incidence in descending order is as follows: USA (104 958 987 people), India (44 684 775 people) and France (39 582 057 people). Russia ranked 10th regarding total COVID-19 incidence (22 137 084 people, including 395 727 fatalities). The infection is able to “overlap” with the underlying pathology, thereby worsening patient’s condition up to death. Lung multislice computed tomography (MSCT) is recommended for all patients with COVID-19. If unavailable, a chest X-ray is performed. The aim of the study was to identify the most frequent comorbid diseases and changes on radiological scan in patients with COVID-19.Materials and methods. The study was carried out at the Infectious Disease Department No. 1, Regional Public Health Institution “Clinical Hospital No. 1” Smolensk. For this, there were analyzed 69 hospital patient records with basic diagnosis — coronavirus infection. The data of anamnesis and additional instrumental investigations were taken into account.&#x0D; Results. 69 patients aged between 18 and 91 years were included in the study. Respiratory failure was not observed in 75.81% of cases. A group of patients (66.67%) with comorbidities of organs and systems was identified, among which most common were: arterial hypertension (95.65%), coronary heart disease (78.26%), diabetes mellitus (30.43%), grade 1–2 obesity (17.39%), chronic hepatitis (17.39%). Diseases of the gastrointestinal tract and respiratory system were less prevalent. The rate of reported complications is as follows: bilateral polysegmental pneumonia — 72.46%; unilateral polysegmental pneumonia — 2.8%; pleurisy — 4.35%; unilateral hydrothorax — 1.45%. Each of the inpatients underwent radiological examination during hospitalisation. X-ray examination accounted for a smaller proportion (39.13%) and multispiral chest computed tomography (MSCT) — for a bigger percentage (60.87%). Chest MSCT at the beginning of inpatient treatment visualized CT-2 stage (64.29%) in the vast majority, less — CT-1 (26.19%), least frequently — CT-3 (7.14%) and CT-4 (2.38%). Before patient discharge, an average of 12.16% improvement in the radiological picture was found in patients with initial CT-1 stage, 14% — in CT-2, 12% and 26% — in CT-3 and CT-4, respectively.Conclusion. The moderate disease course without respiratory depression prevailed among the patients. Co-morbidities were found mainly in the anamnesis of persons over 50 years old. The most frequent clinical complication of coronavirus infection was bilateral pneumonia. After patient’s hospitalization, clinical and instrumental picture gradually improved, which was confirmed by radiological data.
