Material and methods: A retrospective analysis was conducted on patients diagnosed with hepatocellular carcinoma (HCC) confirmed by pathology results from October 2016 to December 2023. Patients were categorized into DPHCC and non-DPHCC (NDPHCC) groups based on immunohistochemical findings. Clinical baseline characteristics and ultrasound features were compared between these groups. Multivariable logistic regression was employed to identify predictive factors. A logisticregression model and nomogram were developed to predict DPHCC.Results: This study included 219 HCC patients (average age: 55.84±9.00, 173 males), with 61 cases of DPHCC and 158 cases of NDPHCC. The results of multivariate logistic regression indicated that halo sign (OR=1.93, p=0.049), PVP hypo-enhancement (OR=2.73, p=0.002) and nodule-in-nodule sign (OR=4.23, p=0.003) were independent predictors of DPHCC. The model's AUC value was 0.73 (95%CI: 0.65-0.80). The calibration curve displayed good predictive accuracy.Conclusions: Ultrasound features, including CEUS, may provide additional information for the non-invasive diagnosis of DPHCC.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"135-142"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142869814","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}

Materials and methods: Patients with surgically proven IDGC (n=85) and benign GB diseases (n=100) were retrospectively enrolled. All patients had preoperative CT and eighty-two patients had US images. Two radiologists independently assessed image findings and analyzed findings suggestive of IDGC and recurrence after surgery. Univariate and multivariate analyses were performed to identify significant predictors for IDGC and recurrence.Results: 87% (74/85) of IDGC belonged to early cancer. On US, mucosal irregularity (odds ratio (OR), 26.29; 95% confidence interval (CI), 2.66-259.42; p=0.005) was a significant predictor of IDGC. Enhancement pattern of wall (OR, 7.78; 95% CI, 2.84-21.39; p<0.001), and maximum wall thickness (OR, 1.31; 95% CI, 1.11-1.55; p=0.002) were significant predictors of IDGC on CT. Twenty-two patients showed recurrence. For clinical factors, T-, N-stage were associated with recurrence (p<0.001). For imaging, focal wall thickening (OR, 8.74; 95% CI, 1.13-67.49, p=0.038) on US and lymph node enlargement (LNE) (OR, 8.93; 95% CI, 1.44-55.19, p=0.018) on CT were significant predictors of recurrence.Conclusion: Image findings are useful to predict IDGC using mucosal disruption, maximum wall thickness, enhancement pattern of wall.

The additional role of two-dimensional shear wave elastography (2D-SWE) in assessing lacrimal gland stiffness was also evaluated.Material and methods: This observational, cross-sectional study included 35 pSS patients and 35 age- and sex-matched healthy controls. LGUS score I incorporated four grey-scale ultrasound parameters, while LGUS score II relied solely on glandular homogeneity. Both scoring systems were evaluated for diagnostic accuracy and interobserver agreement. SWE measurements of lacrimal gland elasticity were also recorded and compared between groups.Results: LGUS score II achieved diagnostic performance comparable to LGUS score I, with areas under the curve (AUC) of 0.831 and 0.829, respectively (p=0.961). Sensitivity was higher for LGUS score II (94.29%) than for LGUS score I (85.70%), with both scores demonstrating identical specificity (68.57%). Interobserver agreement was good for LGUS score II (κ=0.707) and moderate for LGUS score I (κ=0.553). SWE measurements showed no significant differences in mean elasticity values between the pSS and control groups (8.78±2.03 kPa vs. 9.27±2.07 kPa, p=0.158).Conclusion: LGUS score II (glandular homogeneity) offers a reliable, time-efficient diagnostic approach for pSS, providing similar accuracy to the more complex LGUS score I with enhanced interobserver reliability, while the potential of 2D-SWE remains limited by methodological inconsistencies and requires further standardization.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"149-156"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545290","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}
