These scans received an instant review by experts. The discrepancy rates of the resident radiologists were evaluated using expert diagnoses. Then, the plaque detection rate of the resident radiologists was investigated for different plaque characteristics. The causes of incorrect stenosis diagnoses were analyzed.Results: In the investigation of carotid plaque detection, a total of 274 carotid scans from 137 patients were evaluated in our hospital. The overall agreement rate of plaque detection was 90.9%. Echolucent plaques, plaques in the lateral or near wall, and plaques in the carotid bulbs were more likely to be misdiagnosed by resident radiologists. A total of 325 plaques were included in the investigation of carotid artery stenosis classification. The overall agreement rate of stenosis evaluation was 67.7%. The misclassification of moderate stenosis was greater than that of mild and severe stenosis (p=0.0003). The sensitivity was as low as 55.56%. Nonstandard sonographic techniques and incorrect application of interpretive criteria were two main causes.Conclusions: Resident radiologists could accurately and efficiently detect carotid plaques. Scanning by resident radiologists can expand access to ultrasound services. Only the diagnosis of moderate stenosis by resident radiologists was not satisfactory and may require a specialized review from experienced radiologists.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"32-37"},"PeriodicalIF":0.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to analyze the characteristics of conventional ultrasound (US) and contrast-enhanced ultrasonography (CEUS) in HEHE.Material and methods: This multi-center case series study enrolled patients diagnosed with HEHE from five hospitals in China between August 2004 and October 2022. Data on conventional US and CEUS characteristics were collected and analyzed.Results: A total of 41 patients with HEHE were included, comprising 14 males and 27 females with a mean age of 50.62±11.43 years. The mean size of the lesion was 4.51±2.92 cm. Among these patients, 29 were confirmed through surgical resection and 12 through liver biopsy. Conventional US imaging identified three types of HEHE: multifocal type in 35 patients (85.4%), single nodular type in 1 patient (2.4%), and giant type in 5 patients (12.2%). US revealed proximity to the liver capsule in 29 patients (71%), hypoechoic appearance in 36 patients (88%), heterogeneity in 4 patients (10%), and hyperechoic appearance in 1 patient (2.4%). CEUS also demonstrated three distinct enhancement patterns: peripheral marginal enhancement with centripetal filling in the arterial phase and washout in the portal venous and venous phases (23 patients), eterogeneous enhancement in the arterial phase with washout in the subsequent phases (7 patients), and mild hyperenhancement in the arterial phase with resolution in later phases (9 patients). A hypo-enhancement pattern in the portal venous and venous phases was observed in 38 patients, suggesting a higher degree of malignancy.Conclusion: HEHE exhibits specific US findings, primarilypresenting as multiple hypoechoic lesions distributed under the liver capsule.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"12-18"},"PeriodicalIF":0.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Technical efficacy of CNB (success rate) was calculated, and US features were compared between satisfactory CNB specimen and unsatisfactory CNB specimen.Results: Eighty-four SCN per 80 patients (age 64.0±17.2 years, 45.2% female) were included. The optimal SUV cut-off value was 1.1 with diagnostic accuracy of 89.8%. US features associated with malignancy were anteroposterior dimension ≥9 mm and absence of hilum.

The primary outcome, US diagnostic performance, was analyzed across various subgroups including clinical relevance, patient age, and anatomical considerations. The QUADAS-2 tool was employed to assess study quality and minimize bias.Results: From 5,107 initially identified studies, 75 met the inclusion criteria, encompassing 7,769 participants and 3,575 diagnosed fractures. The majority of studies were prospective (79%) and compared US primarily with plain radiography (76%) and CT scans (19%). Of these, 61 studies were amenable to systematic analysis, revealing US to have a sensitivity and specificity of 91% (95% CI: 90%-92%) and 91.3% (95% CI: 90.5%-92.1%), respectively. Likelihood ratios were favorable, with a positive value of 9.955 and a negative value of 0.087, and an odds ratio of 132.67. The area under the curve stood at 0.9715, indicating high diagnostic accuracy despite significant heterogeneity (I²=81.3% for sensitivity, 89.3% for specificity).Conclusion: The evidence supports US as a highly accurate diagnostic tool for bone fractures, rivalling standard imaging methods like CT and radiography. Its notable diagnostic efficacy, combined with advantages in reducing pain, wait times, and radiation exposure, advocates for its broader application. Further validation in large-scale, randomized trials is essential to integrate US more fully into clinical guidelines for fracture management.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"52-62"},"PeriodicalIF":0.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141857470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With new evidence showing that the method is accurate and has excellent performance especially intreatment monitoring and detection of complications of IBD, there is a growing interest in performing this method by thosephysicians who care for IBD patients in in- and outpatient settings. The authors are convinced that intestinal ultrasound is helping to reduce radiation exposure and enables fast and less expensive decision-making by taking patients' needs into account. This paper series contains three parts. This first part summarizes guideline recommendations on the use of ultrasound in IBD, describes the typical findings that can be obtained at the point of care without advanced ultrasound technologies and helps tostandardize documentation. The second part will provide an overview on actual ultrasound-activity-scores in IBD and report about advanced multimodal ultrasound modalities and endoscopic and interventional ultrasound. These modalities should be provided by specialized IBD centers. The third part will enhance a wider overview of treatment control, mural and extramural disease complications as well as extraintestinal manifestations. Advantages and limitations of the method are discussed, with an outlook how to optimize implementation in the future.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
