Endoscopic ultrasound (EUS) offers high-resolution imaging for pancreatic cystic lesions, enabling precise characterization supporting SCNs. We presented EUS features of distinct SCN subtypes, enhancing precise diagnosis preoperatively.Material and methods: This single-center retrospective study was conducted at a tertiary center. We analyzed the clinical, radiological and EUS characteristics of patients with pathologically proved SCN from January 2019 to July 2024.Results: A total of 18 patients were collected. The average age was 49.50 years. 15 out of 18 cases (83.3%) were identified incidentally. Microcystic type accounted for the majority (n=10, 55.6%), followed by macro-cystic type (n=5, 27.8%) and solid type (n=3, 16.6%). No significant differences in radiological imaging were observed among subtypes (p>0.05). EUS features including cyst wall thickening, intra-cystic echogenicity, intralesional vascularity and internal septations, demonstrated significant variations across SCN subtypes (p<0.05). Notably, the stellate scar was a hallmark feature for the microcystic subtype.Conclusions: EUS demonstrates the superior capability in characterizing subtle SCN features, allowing for further subtype classification. Integration of EUS into preoperative diagnostic protocols should be considered for individualized surgical planning.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"145-153"},"PeriodicalIF":2.3,"publicationDate":"2026-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145552497","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}

A 1:1 propensity-score matching was conducted for ultrasound (US) cohort receiving US-guided injections (n=149). The primary endpoint was shoulder pain and disability index (SPADI) scores at 1-month post-injections, with a defined superiority margin of a 10-point decrease. Secondary outcomes included needle insertions, procedure time, range off motion, quality of life (QoL) and adverse events.Results: SPADI scores at 1-month follow-up was 32.81±18.16 and 44.53±11.74 in two cohorts with a mean difference of -11.72 (95%CI: -17.95, -10.48), confirming the superiority (p=0.025).

While muscle ultrasound (US) and shear wave elastography (SWE) offer promise as a non-invasive tool, its role in detecting early muscle loss remains underexplored, especially in the upper limb. Therefore, the aim of this study was to characterize the flexor digitorum profundus (FDP) muscle in older adults with presarcopenia versus normal muscle mass, and to assess the diagnostic potential of grayscale echogenicity and SWE.Material and methods: This cross-sectional study included 50 age- and sex-matched participants classified as presarcopenic (n=25) or normal muscle mass (n=25) based on dual-energy x-ray absorptiometry (DXA)-derived appendicular skeletal muscle mass index (ASMI). All underwent clinical evaluation and ultrasound assessment of the FDP. US parameters included cross-sectional area (CSA), muscle thickness (MT), pennation angle (PA), echogenicity, and SWE in relaxation and contraction. Logistic regression and ROC analysis were applied.Results: Presarcopenic participants had significantly lower CSA (p=0.001) and higher grayscale echogenicity (p<0.001). MT and PA did not differ significantly. Echogenicity showed negative correlations with CSA, DXA measurements, and forearm circumference (FC). Grayscale cut-off values were proposed to differentiate visual echogenicity grades. Although SWE values were not significantly different in univariate analysis, SWE in relaxation emerged as an independent predictor in the regression model.Conclusions: FDP grayscale echogenicity is a strong marker of early muscle decline. SWE in relaxation independently predicted presarcopenia, supporting its role in early diagnostic frameworks. Larger studies are warranted.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"162-171"},"PeriodicalIF":2.3,"publicationDate":"2026-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145491131","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}

Diagnostic sensitivity, specificity, and accuracy were calculated. McNemar's test evaluated differences in performance, Cohen's Kappa measured inter-device agreement, and McNemar's test along with mixed-effects logistic regression analysed the impact of fracture types. Inter-sonographer reliability was assessed using the intraclass correlation coefficient (ICC).Results: Both devices showed 85% sensitivity (95% CI: 61.1-96%). Specificity was low (conventional: 20.0%; handheld: 33.3%). Accuracy was moderate (conventional: 57.1%; handheld: 62.9%).

All patients underwent routine ultrasound, CEUS, and preoperative serum HE4 testing. Adnexal masses were classified using O-RADS and assessed with three CEUS qualitative scores (initial enhancement time, enhancement intensity, and washout pattern) alongside HE4 levels.Results: O-RADS alone showed a sensitivity of 69.2% for borderline and malignant adnexal masses (AUC 0.794). Adding CEUS increased sensitivity to 88.5% (AUC 0.906), and including HE4 further raised it to 96.2% (AUC 0.947). CEUS parameters differed significantly between benign and malignant adnexal masses (p < 0.001). The combined model markedly improved classification of intermediate-risk adnexal masses and reduced misclassification. Interobserver agreement was excellent (Kappa >0.85).Conclusion: The integration of O-RADS with CEUS scoring and HE4 testing significantly improves the diagnostic accuracy for adnexal masses. This improvement is particularly notable in intermediate-risk adnexal masses.
