The scans were conducted both with and without a bowel preparatory protocol (BPP).Results: The highest concordance was observed in the group 4, which included patients with RSE and BPP, with a Kappa value of 0.47-0.52. In contrast, for groups with MRI scans without the BPP, there was no consistency among the investigators (Kappa <0.20). The sensitivity, specificity, positive predictive value, and negative predictive value were 0.72, 0.47, 0.72, and 0.47 without BPP, and increased to 0.82, 0.74, 0.85, and 0.74, respectively, after BPP.Conclusions: The results reveal that the concordance between investigators in detecting RSE via MRI scan improves with the use of BPP. Additionally, the success rate of MRI and TVUS for detecting RSE can be comparable, but only if bowel preparatory techniques are utilized during MRI scans.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"38-43"},"PeriodicalIF":0.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484568","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}

In addition, this study investigates the impact of DL on the diagnostic success of radiologists with different experiences. Material and methods: This study included 576 US images of thyroid nodules. The dataset was divided into 80% training and 20% test sets. Four radiologists with different levels of experience classified the images in the test set as benign-malignant. A DL model was then trained with the train set and predicted benign-malignant for the test set. Then, the output of the DL model for each nodule in the test set was presented to 4 radiologists, who were asked to make a benign-malignant classification again considering these DL results.Results: The accuracy of the DL model was 0.9391. The accuracy for junior resident (JR) 1, JR 2, senior resident (SR), and senior radiologist (Srad) before DL-assisting were 0.7043, 0.7826, 0.8435, and 0.8522 respectively. The accuracy in DL-assisted classifications was 0.9130, 0.8696, 0.9304, and 0.9043 for JR 1, JR2, SR, and Srad, respectively. DL assistance changed the decisions of less experienced radiologists more than more experienced radiologists. Conclusion: The DL model has superior accuracy in classifying thyroid nodules as benign-malignant with US images than radiologists with different levels of experience. Additionally, all radiologists, and most notably less experienced radiology residents, increased their accuracy in DL-assisted predictions.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"26-31"},"PeriodicalIF":0.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142134951","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}

Endoscopic ultrasound (EUS) has advantages of transmural, close range and real-time imaging. Under its guidance, minimally invasive endoscopic removal of FBs and abscess drainage become available and safe to avoid unnecessary surgery. However, relatively few diagnostic applications of EUS have been reported. Endoscopic removal and abscess drainage with or without EUS-guidance were even scarce. We found 21 cases of migratory FBs reported in which EUS was used to diagnose and/or treat including our case. We further summarized clinical characteristics and EUS manifestations of embedded or migratory FBs for future differentiation, and treatment strategies by endoscopy and EUS. EUS is a valuable tool in recognizing and differentiating embedded or migratory FBs. EUS-guided endoscopic removal is a minimally invasive, safe and innovative solution. EUS with novel device also assists in sufficient and secure drainage for FBs related abscess collections. A multidisciplinary team consult is sometimes mandatory for complicated cases. This would break a conceptual barrier in therapeutic endoscopy.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"82-92"},"PeriodicalIF":0.0,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142484565","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}

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}
