Colour Doppler Sonography of the Ovarian Vein: Recognition and Associated Lesions.

The purpose of this study was to evaluate the diagnostic value of colour Doppler sonography for ovarian veins. The clinical incidence of ovarian venous lesions is relatively low and often overlooked. The ovarian veins are located deep in the pelvis, and they are relatively elongated, which could make medical imaging more difficult. Therefore, there is limited literature on the diagnosis of ovarian venous disease. The purpose of this study was to evaluate the diagnostic value of colour Doppler sonography towards ovarian vein. A total of 37 consecutive patients with clinically suspected ovarian venous disorders were included. All the patients underwent colour Doppler sonography. CTV was performed in 31 patients, while retrograde phlebography was performed in 6 patients. CT/phlebography was the established diagnostic criterion for ovarian vein disorders. The SPSS 22.0 program was used for statistical analysis. Sensitivity, specificity, and positive and negative predictive values for colour Doppler sonography were calculated. k-test was used to evaluate consistency between colour Doppler sonography and CT/phlebography. In the 37 patients,18 cases were positive for ovarian vein disorders and 19 cases were negative, as assessed with colour Doppler sonography. The associated lesions included ovarian vein thrombosis (7 cases), ovarian varicocele (3 cases), and ovarian venous leiomyoma (8 cases). The calculated values of sensitivity, specificity, and positive and negative predictive value were 94.4%, 94.7%, 94.4%, and 94.7%, respectively. The overall accuracy rate was 94.9%. The k level of the degree of agreement between CT/phlebography and colour Doppler sonography was 0.892. Colour doppler sonography can provide sufficient imaging information. In clinical ultrasonography, attention should be paid to recognizing and detecting ovarian venous lesions.

Diagnostic value of colour Doppler ultrasound in differentiating malignant and benign nodules in thyroiditis background.

Differentiating malignant thyroid nodules from benign ones is challenging. Sonography is a non-invasive modality that can be helpful in this regard and is far better than invasive methods like fine needle aspiration (FNA). This study aimed to assess the diagnostic value of colour Doppler ultrasonography in distinguishing malignant and benign nodules of thyroid gland. The study involved patients with thyroiditis and thyroid nodules, who underwent sonography. Ultrasound findings were assessed. All the nodules were classified according to the FNA into malignant, follicular nodules and lymphatic. Then, sonography findings were compared between these three groups. There were 216 nodules, including 108 (50%) malignant nodules, 80 (37%) benign and 28 (13%) lymphatic follicles, were evaluated. Micro-calcification was present in 50 (46.3%) malignant cases, 11 (13.7%) benign cases and 2 (2.1%) lymphatic follicles. Decreased or mixed vascularity was reported in 43 (69%) malignant nodules, 4 (5%) benign cases and 7 (25%) lymphatic follicles. Also, 9.7% and 42% of malignant and benign nodules had peripheral circular vascularity, respectively; however, none of the lymphatic follicles had this finding. With 89% specificity, 49% sensitivity and 73.5% accuracy, calcification with or without decreased or mixed vascularity could differentiate benign and malignant nodules. Decreased or mixed vascularity with or without calcification shows high sensitivity in differentiating malignant and benign nodules.

The value of color doppler ultrasonography combined with computed tomography angiography and magnetic resonance angiography in the preoperative quantification and classification of carotid body tumors: a retrospective analysis

BackgroundComputed tomography angiography (CTA) and magnetic resonance angiography (MRA) provide accurate vascular imaging information, but their use may be contraindicated. Color Doppler ultrasonography (CDU) provides simple, safe, noninvasive, and reproducible imaging. We therefore investigated the role of preoperative CDU combined with CTA and MRA in the quantification, typing, and diagnosis of carotid body tumors (CBTs).MethodsWe retrospectively analyzed patients with CBTs categorized into group A (type I [n = 1] and type II [n = 10]) or group B (type III [n = 56]) per the intraoperative Shamblin classification. CDU, CTA, and MRA characteristics of CBTs were observed, surgical results were correlated, and the diagnostic threshold of the CBT classification was calculated.ResultsCBTs were usually located at the common carotid artery bifurcation, encircling the carotid artery. An increased angle was found between the internal and external carotid arteries. On CDU, CBTs primarily presented as homogeneous hypoechoic masses with clear boundaries, rich flow signals, and a high-speed, low-resistance artery-like flow spectrum. CTA showed uniform or heterogeneous marked enhancement. MRA showed mixed T1 and slightly longer T2 signals and uniform or uneven obvious enhancement. With increases in the lesion size, amount of blood transfused, and operation time, the intraoperative classification level and possibility of skull-base invasion increased. When the maximum diameter of the lesion, the volume of the tumor, the distance between the upper margin of the tumor to the mastoid and the mandibular angle were 3.10 cm, 10.15 cm3, − 3.26 cm, and 0.57 cm, respectively, the largest Youden index was the best diagnostic boundary value for Shamblin type III tumors.ConclusionsCDU combined with CTA and MRA can accurately evaluate the size and classification of CBTs.

The value of color Doppler ultrasonography combined with serum tumor markers in differential diagnosis of gastric stromal tumor and gastric cancer.

This study aimed to explore the value of color Doppler ultrasonography combined with carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) in differential diagnosis of gastric stromal tumor (GST) and gastric cancer (GC). An analysis of the clinical data of 180 patients with clinically suspected gastric space occupying lesions. According to the postoperative pathological results, 180 suspected gastric space-occupying lesion patients were divided into GST group (n = 83) and GC group (n = 97). Color Doppler ultrasonography, serum tumor markers CEA and CA19-9 were compared. The research results showed that serum CEA and CA19-9 levels were lower in patients with GST group than those with GC group (both P < 0.001). With postoperative pathology as the gold standard, detection rates of GST and GC by combination of color Doppler ultrasound (CDUS), serum CEA, and CA19-9 were higher than those of each index alone (both P < 0.001). There was no difference between detection rates of GST and GC by combination of CDUS, serum CEA, and CA19-9 (P = 0.058). Color Doppler ultrasonography combined with serum tumor markers CEA and CA19-9 tests has a certain differential diagnostic value for GST and GC, which may provide a reliable reference basis for clinical diagnosis and treatment.

Clinical use of color Doppler ultrasonography to predict and evaluate the collateral development of two common revascularizations in patients with moyamoya disease.

To explore the value of color Doppler ultrasonography (CDU) to predict preoperatively and evaluate postoperatively the collateral development of two common revascularizations in patients with moyamoya disease (MMD). We prospectively enrolled 49 patients with MMD who underwent unilateral superficial temporal artery (STA) -middle cerebral artery (MCA) anastomosis or encephalo-duro-arterio-synangiosis (EDAS). The parameters of the extracranial arteries, including STA, internal carotid artery (ICA), external carotid artery (ECA), and vertebral artery (VA), were performed before and at 3-6 months after surgery. DSA results were used to assess surgical collateral development. To predict good collateral development before STA-MCA anastomosis, the preoperative D > 1.75 mm in the STA had the highest area under the Receiver Operating Characteristic curve (AUC). To predict good collateral development before EDAS, the preoperative EDV > 12.00 cm/s in the STA had the highest AUC. To evaluate the good collateral development after STA-MCA anastomosis, the postoperative EDV > 16.50 cm/s in the STA had the highest AUC. To evaluate the good collateral development after EDAS, an increase of D of 0.15 mm in the STA had the highest AUC. Logistic regression analysis showed that the preoperative RI and EDV in the STA were highly correlated with collateral development. Besides, the preoperative RI was an independent risk factor for collateral development. CDU could predict preoperatively and evaluate postoperatively the collateral development of STA-MCA anastomosis and EDAS surgery postoperatively by detecting ultrasound parameters of the STA.

Application of Color Doppler Ultrasound Combined with Magnetic Resonance Imaging in Placenta Accreta.

In order to improve the diagnostic value of color Doppler ultrasonography in placenta accreta and make the diagnosis more accurate, a method to detect placenta accreta by combining color Doppler ultrasonography and magnetic resonance is proposed. The patients with placenta accreta were selected for color Doppler ultrasonography and MRI examination. Kappa test was used to analyze the consistency between the results of ultrasound and MRI examination alone and combined diagnosis and pathological examination results, and the receiver operating characteristic (ROC) was drawn. Price compliance, sensitivity, specificity, good estimate rate, negative bid success rate, and Youden index were chosen as the basis for measuring the value of our tests. The results showed that the Kappa combined test rate was 0.609, the equivalent efficiency was 80.90%, and the correlation was good; ROC curve analysis showed that the sensitivity and specificity of articular placenta accreta were 91.75% and 89.26%. The sensitivity, uniqueness, good estimate, negative predictive value, and Youden index of color Doppler ultrasound combined with magnetic resonance imaging>magnetic resonance imaging>color Doppler ultrasound in our laboratory were compared, and the difference was significant (P < 0.05). The experimental results show that color Doppler ultrasound and MRI are effective in the diagnosis of placenta accreta, and each has advantages and disadvantages. Therefore, it has been improved in the diagnosis of placenta accreta, is helpful for the diagnosis of placenta accreta, and is suitable for popularization and use.

Application of Color Doppler Ultrasound in Microscopic Imaging Diagnosis of Adenomyosis.

In order to explore the value of color Doppler ultrasonography (TVCDS) in the diagnosis and differential diagnosis of adenomyosis. A total of 150 patients with adenomyosis admitted to a hospital from January 2020 to December 2021 were selected, taking transvaginal three-dimensional color Doppler ultrasound and abdominal ultrasound for examination, all results were compared with patient pathology or surgical results, in order to compare the accuracy of the two inspection methods. The positive predictive value of three-dimensional color Doppler ultrasonography was higher than that of abdominal ultrasonography, and the difference was statistically significant (P < 0.05). The coincidence rate, sensitivity, and specificity of three-dimensional color Doppler ultrasonography were higher than those of abdominal ultrasonography, while the misdiagnosis rate was lower than that of abdominal ultrasonography, and the differences were statistically significant (all P < 0.05). The imaging features of vaginal three-dimensional color Doppler ultrasound in patients with adenomyosis are mainly enlarged uterus, slightly stronger echoes in the myometrium with enhanced echogenic spots, and short or short branch blood flow signals in the lesions. After statistical analysis, there was a significant difference in the blood flow changes between benign and malignant endometrial echoes and abnormal echoes in the uterine cavity, P < 0.05. Normal endometrium and benign intrauterine lesions mainly showed no blood flow signal, while malignant lesions in the uterine cavity mostly showed changes in blood flow signal. Compared with abdominal examination, transvaginal color Doppler ultrasonography has obvious advantages in the diagnosis of adenomyosis. According to the characteristics of ultrasound images, blood flow distribution, frequency spectrum, etc., it can provide a more accurate basis for clinical timely, provide the identification points of uterine fibroids, and provide help for clinicians to choose a treatment plan.

Application Value of Color Doppler Ultrasonography Combined with Thyroid Autoantibody Tests in Early Diagnosis of Thyroid Cancer.

Objective To explore the application value of color Doppler ultrasonography combined with thyroid autoantibody tests in the early diagnosis of thyroid cancer. Methods The medical data of 100 patients with thyroid nodules treated in our hospital from June 2019 to June 2021 were retrospectively analyzed; all patients received color Doppler ultrasonography and thyroid autoantibody tests before surgery and were divided into the benign lesion group (n = 45) and the malignant lesion group (n = 55) according to the postoperative pathological findings (the gold standard), so as to compare and analyze the application value of color Doppler ultrasonography, thyroid autoantibody tests, and their combination in the early diagnosis of thyroid cancer. Results Compared with the pathological findings, the accuracy rate, sensitivity, specificity, positive predictive value, and negative predictive value of the combined diagnosis were significantly higher than those in the single diagnosis of color Doppler ultrasonography, TgAb test, TPOAb test, and TRAb test (P < 0.05), and by plotting the ROC curves to analyze the effect of these modalities in diagnosing early thyroid diseases, the results showed that the areas under the curve from large to small were combined diagnosis, color Doppler ultrasonography, TgAb test, TPOAb test, and TRAb test. Conclusion Color Doppler ultrasonography has many advantages in the diagnosis of thyroid nodules, such as easy operation, painlessness, noninvasiveness, high efficiency, and repeatable detection, and the high-definition probe is able to show tiny lesions, echogenicity, blood flow signal, and other characteristics of foci. Combining color Doppler ultrasonography with testing thyroid autoantibodies such as TgAb, TPOAb, and TRAb can effectively improve the detection rate of early thyroid cancer, presenting significant reference value and meaning to clinical diagnosis and treatment of thyroid cancer.

The value of color Doppler sonography in diagnosis and hemodynamic analysis of innominate artery occlusion

The occlusion of the innominate artery caused a significant decrease in the distal end of the right subclavian artery and the right common carotid artery, internal carotid artery, and external carotid artery (ECA). Due to the different pressure and the abundant communicating arteries between the ECA and the bilateral vertebral artery (VA), different paths of blood steal in the anterior and posterior circulation occurred.

The value of color doppler ultrasonography in the diagnosis of endograft infections following endovascular aneurysm repair

Objective: To study the value of color doppler ultrasonography (CDU) in the diagnosis of endograft infections following endovascular aneurysm repair (EVAR). Methods: The retrospective analysis of post-EVAR stent infections identified by computed tomography angiography (CTA) was conducted at the First Affiliated Hospital of Sun Yat-sen University from January 2010 to December 2020. There were 16 males and 4 females, aged from 49 to 86 years. All the patients were detected by CDU. The endoleak, bubbles, abscess, hematoma, aortic intestinal fistula (AEF) and occlusion of stent detected by CTA and CDU were analyzed and compared. Results: Among 20 patients, 9 cases with endoleak were detected by CTA, while CDU showed 8 cases with endoleak. The rate of missed diagnosis was 1/9. The misdiagnosis rate was 0, and the Youden index was 0.89. CDU detected 3 cases with type Ⅱ endoleak, and 1 case was missed when compared with CTA. Three cases with type Ⅰa and 2 cases with type Ⅰb were detected by CDU, which were consistent with those of CTA. CDU and CTA showed that there were no cases with type Ⅲ and type Ⅳ endoleaks. CDU detected 8 cases with bubbles in the sac. Compared with CTA, the rate of missed diagnosis was 2/10. The misdiagnosis rate was 0, and the Youden index was 0.80. The cases with abscess, hematoma, increasing size of the aneurysm, occlusion of stent and fluid sonolucent area in the sac detected by CDU were 8/20, 2/20, 4/20, 1/20, 2/20, which were consistent with CTA. CDU did not detect the 3 cases with aortoenteric fistula(AEF) which were identified by CTA. The follow-up of CDU showed that the extra-anatomic bypasses remained their patency in 5 cases, 1 case occurred bypass occlusion. The range of infectious area and bubbles reduced in 2 cases. There was no change of endoleak in 1 case. All the follow-up results were consistent with those of CTA. Conclusion: CDU can comprehensively evaluate the infection in and around the aneurysm in patients with stentinfection after EVAR, with a high auuraly, and has important clinical significance for the early diagnosis, treatment and prognosis of patients.

The Role of Color Doppler Ultrasonography and Magnetic Resonance in the Prenatal Diagnosis of Placenta Accrete

Background: Placenta accrete is a clinical and diagnostic challenge that is being with increasing frequency and may lead to catastrophic blood loss and related complications. Color doppler ultrasonography and magnetic resonance imaging are considered as specific imaging modalities and have very important role in the prenatal diagnosis of placenta accreta. Objectives: The aim of the current work was to evaluate the diagnostic value of color doppler ultrasonography and magnetic resonance imaging in the prenatal assessment of placenta accreta. Patients and Methods: This study was conducted on 40 pregnant women (from 32 to 40 weeks of pregnancy) with placenta previa and presented with manifestations of suspected placenta accreta. Their age ranged from 19 to 40 years with mean age of 31.8 years. All cases were subjected to ultrasound examination, but MRI was done in 33 cases prior to elective delivery. Results: Cases diagnosed of having placenta accreta were 18 out of 40 cases (45 %). Among those 18 cases; placenta found tobe accreta in 6 patients, increta in 7 patients and percreta in 5 patients. Our study showed high statistical significance between occurrence of Placenta accrete & prior uterine surgeries as a risk factor. Overall accuracy of ultrasound was 88%, while that of MRI was 85%. Ultrasound showed better specificity (86%) than that of MRI (81%), but MRI showed better sensitivity (92%) than that of ultrasound (89%). Conclusion: It could be concluded that both ultrasound and magnetic resonance have fairly good sensitivity and specificity for prenatal diagnosis of placenta accreta. Color doppler ultrasound remains the first primary screening imaging modality used to evaluate suspected placenta accreta and MRI is suggested as an alternative complementary tool to ultrasound in cases with inconclusive criteria.

The Role of Color Doppler Ultrasonography in the Perioperative Period of Coronary Artery Bypass Grafting: Comparison with Transit-Time Flow Measurement

Introduction: The value of color Doppler ultrasonography (CDUS) with the supraclavicular approach for preoperative evaluation of the native left internal mammary artery (LIMA) as well as for the postoperative detection of LIMA graft patency was recently suggested. However, the parameters such as the flow volume and pulsatile index (PI) have not been studied in detail. Objectives: The objectives of this study were to analyze the LIMA data in the perioperative period and explore the relationships between the intraoperative graft flow with transit-time flow measurement (TTFM) and the postoperatively measured parameters with CDUS. Methods: Fifty-eight patients with significant stenosis (≥70%) or occlusions in left anterior descending artery (LAD) who were referred for isolated coronary artery bypass grafting (CABG) were enrolled in this study and examined by CDUS prior to CABG from April to July 2016. The perioperative measurements of proximal LIMA by CDUS were compared. In addition, the correlation between the intraoperative graft flow, such as the mean graft flow (MGF) and PI, and the immediate postoperative measurements of CDUS in LIMA bypassed grafts was statistically analyzed. Results: Six patients were excluded due to screening failure, or insufficient visualization of CDUS images for analysis. Fifty-two patients with in situ LIMA-LAD graft, with or without additional arterial grafts or saphenous vein grafts, were included in the final analysis. The postoperative diameters of proximal LIMA were not significantly different from preoperative diameters (2.21 ± 0.18 vs. 2.27 ± 0.22 mm, p = 0.070). The flow volume on the early postoperative CDUS significantly increased (39.77 ± 21.59 vs. 25.96 ± 13.17 mL/min, p < 0.001) and the PI significantly decreased (1.43 ± 0.46 vs. 4.20 ± 1.49, p < 0.001) versus those of preoperative measurements. The MGF had a moderate correlation with the flow volume on the early postoperative CDUS (r = 0.414, p = 0.002), and the PI by TTFM had a weak correlation with that by CDUS (r = 0.353, p = 0.010) as well. Conclusions: The MGF and PI by TTFM in CABG were associated with in situ LIMA graft parameters measured by CDUS studies. CDUS is a useful functional noninvasive tool for the preoperative screening and postoperative follow-up of patients with in situ LIMA bypass.

The value of color doppler ultrasonography in the diagnosis of impending ruptured abdominal aortic aneurysm

Objective: To study the value of color doppler ultrasonography (CDU) in diagnosis of impending ruptured abdominal aortic aneurysm (IRAAA). Methods: A total of 35 cases with IRAAA which were identified by CDU in our department from June 2014 to June 2019 were retrospectively analyzed. All the patients were detected by computed tomographic angiography (CTA). The types, length of the neck of aneurysm, largest diameter, thrombosis, involvement of common iliac artery and impending ruptured conditions were compared. The postoperative patients were followed-up by CDU and CTA (mean time was 2.6 months). Results: Among 35 patients, CDU diagnosed that 5 cases were pararenal types and 30 cases were infrarenal types. CTA showed that 4 cases were pararenal types and 31 cases were infrarenal types. The misdiagnosis rate of CDU was 2.9% (1/35). CDU showed that bilateral common iliac arteries were involved in 21 cases, right common iliac arteries were involved in 3 cases, and left common iliac arteries were involved in 2 cases. CTA detected the same results. There was no statistical difference between CDU and CTA for detection of the largest anteroposterior diameter, transverse diameter and the thickness of thrombosis (P values were 0.354, 0.310 and 0.865). There was statistical difference in the detection of the length of the aneurysm's neck (P=0.006). CDU showed 3 cases of focal wall discontinuity, 4 cases of hyperattenuating crescent sign, 3 cases of thrombus fissuration and 2 cases of saclike protuberance, which were consistent with the detection of CTA. CDU showed that locally thin wall of aneurysm was detected in the rest of 23 cases. CTA showed 2 patients were negative. The misdiagnosis rate of CDU was 5.7% (2/35). Three cases did not undergo surgery. Open repairs (OR) were performed in 5 cases. Endovascular aneurysm repairs (EVAR) were performed in 27 cases. The postoperative patients were followed up by CDU and CTA at 1 month, 3 months, 6 months and 12 months. All the artificial blood vessels and stents were patent. Endoleak was observed in 5 cases. Aneurysm sac thrombosis was found in the rest of the cases. Conclusions: CDU plays an important role in the analysis and diagnosis of the size, range, and the impending ruptured symptoms of the aneurysm. It provides a reliable basis for IRAAA screening, diagnosis and postoperative follow-up, and has important clinical value.
