Imaging findings were compared with histopathology to assess diagnostic performance. Associations between nonalcoholic fatty liver disease activity score (NAS), fibrosis stage, and imaging parameters were also evaluated.</p><p><strong>Results: </strong>A total of 121 patients were included. The median age was 50 years, and 57 (41%) were male. Histology confirmed steatotic liver disease in 43 cases. Excellent interobserver agreement was observed for UDFF (ICC = 0.974), pSWE (ICC = 0.958), and auto-pSWE (ICC = 0.960). UDFF showed a stepwise increase with steatosis grade and was moderately correlated with histological fat content (r = 0.676 for Sonographer 1, r = 0.638 for Sonographer 2; P < .001). For detecting S ≥ 1 steatosis, the optimal UDFF thresholds were ≥8.4% (Area Under the Curve (AUC) = 0.968; Se = 92.5%, Sp = 93.2%) for Sonographer 1 and ≥8.6% (AUC = 0.951; Se = 90.0%, Sp = 86.3%) for Sonographer 2. For moderate steatosis (S ≥ 2), the cutoffs were ≥10.4% (AUC = 0.932; Se = 100%, Sp = 79.6%) and ≥10.6% (AUC = 0.925; Se = 100%, Sp = 76.5%), and for severe steatosis (S = 3), ≥18.3% (AUC = 0.961; Se = 100%, Sp = 77.4%) and ≥18.7% (AUC = 0.949; Se = 100%, Sp = 77.4%) for Sonographer 1 and 2, respectively. UDFF positively correlated with body mass index and subcutaneous fat thickness, and negatively with both pSWE and auto-pSWE. A strong correlation was observed between pSWE and auto-pSWE for both observers. A weak positive correlation was found between NAS and auto-pSWE in MASLD cases. The optimal thresholds to detect fibrosis (≥F1) were 5.05 and 4.95 kPa for Sonographer 1, and 5.05 and 4.85 kPa for Sonographer 2, for pSWE and auto-pSWE measurements, respectively.</p><p><strong>Conclusion: </strong>DAX-derived UDFF and auto-pSWE are reproducible, noninvasive biomarkers with strong diagnostic value in assessing steatosis and fibrosis in MASLD.</p>","PeriodicalId":17563,"journal":{"name":"Journal of Ultrasound in Medicine","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144690657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The exosome regions were compared with the contralateral (non-treated) areas and adjacent tissues before and after application. Hyperechoic islets in the upper hypodermis and an increase in dermal vascularity were detected in these cases, forming a consistent pattern in the 3 cases at the exosome regions. This may be related to a mild degree of inflammation and neoangiogenesis in the treated regions. In 1 patient with alopecia, there was evidence of hair follicle growth at the exosome area. Further investigations are needed to examine the persistence of these changes over time and the impact of local trauma on the ultrasonographic abnormalities resulting from the application of these agents.
