Both used a block design with six trained sonographers scanning six healthy liver volunteers using the same machine. Following training, each sonographer obtained ten SWE measurements from the right liver lobe for each volunteer per manufacturer guidelines.Results: When patients were scanned on different days, intraclass correlation coefficient (ICC)=0.23 was achieved, and when scanned on the same day, ICC=0.83, indicating that 17% of the variability was due to differences between sonographers. This 17% inter-sonographer variability translated into statistical and potentially clinically significant differences between sonographers-one sonographer had a SWE value of (4.99) and another (5.43), p<0.01, almost passing a clinical threshold.Conclusion: SWE values are influenced by a sonographer effect, highlighting the need to standardize protocols to minimize systematic variability between sonographers. Multiple scans are justified for patients with SWE values near clinical thresholds. Since healthy volunteers exceeded the manufacturer-defined threshold, inherent variability between sonographers could challenge the reliability of clinical thresholds in practice.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311127","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}

Treatment success was defined as ≥50% improvement in the NRS score at the 6-month follow-up. Demographic, clinical, and procedural factors were analyzed.Results: The successful treatment group (n=26, 44.8%) showed significant reduction in median NRS pain scores from 7.00 to 2.00 (p<0.001) and marked improvement in ODI functional scores. Factors significantly associated with success included younger age (p=0.02), lower BMI (p<0.001), shorter symptom duration (p<0.001), nonsmoking status (p<0.001), and absence of previous spinal (p=0.03) or hip surgery (p=0.04).

Traditionally, ultrasound was predominantly taught during postgraduate medical training. However, today ultrasound education is increasingly being incorporated into preclinical curricula of medical students. Although extensive literature on individual ultrasound training programs is available, research on the effective development and implementation of ultrasound education for students remains limited. This article identified five key considerations for incorporating student ultrasound education into existing medical curricula, based on an analysis of working examples in various parts of the world: The synergistic relationship between anatomy and ultrasound, didactic evolutions such peer-assisted learning, the role of Point-of-Care-Ultrasound (POCUS) and e-Learning in resource-limited settings, the considerations of possible side effects and lastly, the early engagement with key stakeholders. These five key considerationsshould help the successful and long-term development, adaptation and implementation of a new or existing ultrasound education program in undergraduate education, thereby contributing to the training of competent future healthcare professionals.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311126","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, we conducted a subgroup analysis comparing the ultrasonographic features of gynecomastia and malignant nodules in male breasts.Results: Differences were found in age of onset, calcifications, aspect ratio greater than 1/2, Adler grading of blood flow, and axillary lymph nodes. The presence of calcifications was an independent risk factor for malignancy in males. The results of the comparison between gynecomastia and breast cancer were essentially consistent with the former. However, the differences in calcifications were not as significant as those observed in the former.Conclusions: We identified differences in age of onset, calcification, aspect ratio greater than 1/2, blood flow, and axillary lymph nodes between benign and malignant male breast nodules classified as Breast Imaging Reporting and Data System category 4, with calcification being an independent risk factor for malignancy.

An ultrasound-guided catheter-over-needle technique was proposed to reduce this risk. This study compared the incidence of vascular injections between the catheter-over-needle and Tuohy needle methods for caudal epidural injections.Material and methods: This prospective, randomized clinical trial included patients aged ≥19 years with degenerative lumbar disease accompanied by radicular pain who were unresponsive to non-invasive treatments and scheduled for caudal epidural injection. The participants were randomized into two groups: catheter-over-needle and Tuohy needle groups. Under ultrasound guidance, the contrast medium was injected and observed in real time using fluoroscopy. An independent physician assessed the vascular injection rates.Results: The incidence of vascular injection was significantly lower in the catheter-over-needle group (15.7%) than in the Tuohy needle group (37.5%; p=0.014). Chronic pain lasting >12 months was a significant risk factor for vascular injection (p=0.035). However, no statistically significant association was found between sacral opening depth and vascular injection, although the sacral opening depth was shorter in patients who received intravascular injections.Conclusions: The catheter-over-needle technique significantly reduces the risk of vascular injection. The depth of the sacral opening may also influence vascular injection.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144061253","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}
