The elastic properties of the ascending aorta, thoracic aorta, and abdominal aorta were assessed by diameter strain (DS) which was determined by M-mode echocardiography. DS was defined as 100 × (Dmax - Dmin)/Dmin. Correlations between DS and gestational age and combined cardiac output were assessed by linear regression analysis.Results: We successfully acquired 377 (93.8%) normal fetal measurements. DS of the ascending aorta, thoracic aorta, and abdominal aorta declined as the gestational age proceeded (b = -0.683, -0.358 and -0.263, p < 0.001), while it increased with combined cardiac output (b = 0.041, 0.03, and 0.017, p < 0.001). DS in the ascending aorta and thoracic aorta were higher than those in the abdominal aorta (p < 0.001), while there was no significant difference between the ascending aorta and thoracic aorta. The reproducibility for DS measurements by M-mode echocardiography was good.Conclusions: Our results demonstrated a decline in DS with gestational age and variable aortic strain from the proximal to distal segments in the normal fetuses. Intrauterine changes in arterial elastic properties might reflect the maturation of fetal circulation.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144009348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings of ultrasound (US) and magnetic resonance imaging (MRI) were compared to histology as the reference.Results: Among 78 patients, 46.2% of cases were menopause. Abnormal vaginal bleeding was the most common symptom. Three common types of uterine sarcoma were leiomyosarcoma (50.0%), low-grade endometrial stromal sarcoma (23.1%), and carcinosarcoma (19.2%). Some imaging features of uterine sarcomas were found including nontypical lesion of fibroid (89.7%), solitary mass (84.6%), inhomogeneous structure (76.9%), invisible endometrium (67.9%), moderate-rich vascularization on Doppler signal (57.7%), irregular border of tumor (48.7%), classification of FIGO 0 (44.9%), cystic area within tumor (42.3%), acoustic shadowing (34.6%), \"cooked\" appearance (9.0%), and calcification image in tumor (6.4%). The sensitivity of standard US, consultant US, and MRI was 56.4%, 88.4%, and 87.5%, respectively.Conclusions: Besides clinical presentations, uterine sarcomas present some specific features on US. Consultant US and MRI could be added to standard US to increase the accuracy and help in surgical decision making where applicable.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143967795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental aspect will therefore involve the contribution of the classical CNN, as well as models inspired by this CNN, namely, Inception V3, ResNet 50, AlexNet, and EfficientNet in addition to the hybrid architecture.Results: The conducted experiments entailed the adjustment of multiple hyperparameters, leading to the development of an architecture that achieved optimal results. Additionally, employing a hybrid architecture not only facilitated the amalgamation of the strengths from two models (the top performing pretrained ResNet50 model with the Vision Transformer) but also led to enhanced accuracy. After training the dataset, the proposed models have contributed to progressively improving the results, eventually achieving a classification rate of 95.53% for the hybrid ResNet50-ViT model.Conclusion: The aim of this research is to equip clinicians with a robust tool for melanoma diagnosis by leveraging the strengths of two models within the ResNet50-ViT hybrid framework.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quality was assessed using the QUADAS-2 tool. Quantitative meta-analysis was performed.Results: Nine articles comprising 3924 women (3979 adnexal masses) were ultimately included after exclusions. Three studies compared O-RADS versus SR, three studies compared O-RADS versus ADNEX, and three studies compared all three methods. The risk of bias was high for patient selection in QUADAS-2 in all studies. Six studies compared O-RADS versus SR; no significant differences were found (pooled sensitivity and specificity of O-RADS and IOTA SR were 94.0% and 77.0%, and 91.0% and 87.0%, respectively. p = 0.2204).
