Of these, 590 were from the retrospective dataset and 445 cases were from the prospective dataset. The diagnostic accuracy of the dynamic AI system in the thyroid nodules was evaluated in comparison to the gold standard of postoperative pathology. The sensitivity, specificity, ROC, and diagnostic differences in the κ-factor relative to the gold standard were analyzed for the AI system and the FNA.Results: The dynamic AI diagnostic system showed good diagnostic stability in different ages and sexes and nodules of different sizes. The diagnostic AUC of the dynamic AI system showed a significant improvement from 0.89 to 0.93 compared to ACR TI-RADS. Compared to that of FNA cytopathology, the diagnostic efficacy of the dynamic AI system was found to be no statistical difference in both the retrospective cohort and the prospective cohort.Conclusion: The dynamic AI diagnostic system enhances the accuracy of ACR TI-RADS-based diagnoses and has the potential to replace biopsies, thus reducing the necessity for invasive procedures in patients.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143994245","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}

Anxiety levels were assessed using the Beck Anxiety Inventory, while temporomandibular disorder severity was determined by the Fonseca Anamnestic Index. Masseter muscle thickness, length, and cross-sectional area were measured bilaterally at rest and during intercuspation using a high-frequency linear probe. Statistical analyses were conducted based on temporomandibular disorder severity, anxiety, gender, and chewing side preference.Results: Participants with disc displacement exhibited significantly increased masseter thickness on the affected side at both rest and intercuspation (p < 0.05), whereas muscle length and cross-sectional area remained unchanged. Individuals with severe anxiety had a significantly greater cross-sectional area compared to those with normal anxiety (p < 0.05), while thickness and length showed no significant differences. Males had significantly greater masseter thickness, length, and cross-sectional area than females (p < 0.05). No significant differences were found concerning chewing side preference (p > 0.05).Conclusion: Temporomandibular disorders and anxiety influence masseter morphology, with variations based on severity and duration. Gender differences were evident, whereas chewing side preference had no significant effect. Ultrasonography proves to be a reliable tool for masseter evaluation, though future studies should incorporate advanced imaging and functional assessments.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144002908","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 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}
