Intestinal ultrasound (IUS) is used to measure bowel wall thickness (BWT). The aim of our study was to measure BWT in IBS-D patients, ulcerative colitis (UC) and healthy controls (HC), and compare BWT, IBS-SSS score, and FC level.Material and method: Patients with IBS-D and symptom exacerbation (n=100), active UC (n=25), and HC (n=30) were included. FC was measured in all groups. IBS-D patients with an IBS-SSS score >75 and FC level >50 µg/g underwent IUS and colonoscopy.Results: Patients with IBS-D had a (mean±SEM) IBS-SSS score of 268±11, FC level of 260±46 µg/g, and a normal colonoscopy. IUS showed a significant difference (p<0.0001) between sigmoid BWT for IBS-D (3.16±0.09 mm) and HC (1.6±0.12 mm). Color Doppler signals were also absent. A significant correlation between sigmoid BWT and FC level (r=0.48, p=0.0012) was found in patients with IBS-D.Conclusion: Compared to HC, sigmoid BWT was significantly increased in IBS-D patients with symptom exacerbation. Sigmoid BWT correlates significantly with FC levels during IBS-D symptom exacerbation.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"263-270"},"PeriodicalIF":2.3,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147481515","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}

All the patients underwent both 2DTVUS and CEUS. 2DTVUS was used to assess myometrial thickness at the scar, gestational sac protrusion, and vascularity. CEUS was used to evaluate the enhancement pattern, time-to-peak, and peak intensity relative to the adjacent myometrium.Results: Histopathology confirmed 63 cases of CSP and 43 cases of non-CSP among the 106 patients who subsequently underwent pregnancy termination. 2DTVUS identified 95 cases as CSPs and 11 as non-CSPs, whereas CEUS identified 66 cases as CSPs and 40 as non-CSPs. Compared with 2DTVUS, CEUS showed higher specificity (97.6% vs. 63.4%, p<0.001), sensitivity (96.9% vs. 92.3%), accuracy (97.2% vs. 81.1%, p<0.001), positive predictive value (98.4% vs. 80.0%, p=0.0018), and negative predictive value (95.2% vs. 83.9%). ROC analysis demonstrated that CEUS had a higher AUC than 2DTVUS (0.972 vs. 0.779, p<0.001).Conclusion: CEUS complements 2DTVUS by sensitively depicting microvascular perfusion and quantifying the relationship between the gestational sac and the cesarean scar, thereby improving diagnostic accuracy and facilitating preoperative planning in patients with suspected CSP.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149043231","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}

However, contemporary ultrasonographic findings are frequently described using historically evolved, metaphorical, and ambiguously defined terms. This semantic variability limits reproducibility, data harmonization, and the learning and reporting capacity of AI-based models. Ultrasound images do not represent direct anatomical depictions, but rather algorithmic reconstructions of acoustic interactions based on model-dependent assumptions. Artifacts and echo patterns, therefore, reflect the discrepancy between physical reality and mathematical approximation within signal processing. Inconsistent nomenclature widens the gap between measured variables, reconstruction models, and clinical interpretation. This paper analyses this structural problem and outlines a development framework for an internationally compatible Terminologia Sonographica. It proposes the systematic collection of existing descriptors, their translation into operationalizable categories, and consensus-based validation involving ultrasound societies. The aim is to establish an ontologically precise, interoperable semantic infrastructure for quality assurance, digital documentation, and future AI-supported decision-making.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149043234","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}

Outcomes included Numeric Rating Scale-sitting (NRS-sitting), sitting tolerance, and Patient Global Impression of Change (PGIC) over 8 weeks.Results: Feasibility endpoints were met with no complications. NRS-sitting decreased from 6.33±1.23 to 2.17±0.72 at week 8 (95% CI: 1.71-2.63; p<0.001). At week 8, 58.3% of patients could sit for >30 minutes, and 75% reported high satisfaction (PGIC scores of 6 or 7). Findings should be interpreted as preliminary feasibility and short-term clinical outcomes of the staged intervention algorithm.Conclusion: These preliminary findings suggest that a staged ultrasound-guided approach incorporating PRF is feasible and safe for refractory coccydynia, with short-term improvements in pain and functional sitting tolerance reflecting the overall staged protocol rather than the isolated effect of PRF. Larger randomized controlled trials with longer follow-up are required to determine clinical efficacy, long-term durability, and the incremental contribution of PRF.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149043200","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}

We extracted 3,499 radiomic features from pre-procedural ultrasound images and combined them with clinicopathological variables to train seven machine learning classifiers using 10-fold cross-validation.

With H-CEUS mode, the senior physician and two beginners demonstrated strong interobserver agreement in assessing both the number (p<0.001) and distribution (p<0.001) of IPN.
