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}

Reference points are made allowing the measurement of this sulcular space. To assess the hypothesis of normality of the data, a Kolmogorov-Smirnov test was performed for each of the samples due to the size of their population (>50). To complete this test, Lin's concordance test was also applied.Results: A total of 348 manual probing and 348 ultrasound imagines measurements were performed. The Lin concordance and correlation coefficients and their 95% confidence intervals obtained were 0.855 (95% CI [0.822; 0.855]). These data allow us to demonstrate the equivalence between the measurement of the depth of the periodontal pocket by ultrasound imaging and the measurement by manual probing.Conclusion: This study shows that the use of an ultrasound probe for periodontal imaging was comparable to the current gold standard for measuring the sulcus area.

Univariate and multivariate analyses of traditional clinical features were performed to establish a logistic regression model. Ultrasound-based radiomics features are extracted from grayscale images after delineating regions of interest (ROIs). Independent samples t-tests, Mann-Whitney U tests, and Least Absolute Shrinkage and Selection Operator (LASSO) regression were employed to select ultrasound-based radiomics features. Subsequently, five machine learning methods were used to construct radiomics models based on the selected features. Model performance was evaluated using receiver operating characteristic (ROC) curves and the Delong test.Results: Age, poorly defined margins, and irregular shape were identified as independent risk factors for malignant skin tumors. The multilayer perception (MLP) model achieved the best performance, with area under the curve (AUC) values of 0.963 and 0.912, respectively. The results of DeLong's test revealed a statistically significant discrepancy in efficacy between the MLP and clinical models (Z=2.611, p=0.009).Conclusion: Machine learning based skin tumor models may serve as a potential non-invasive method to improve diagnostic efficiency.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144002249","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}
