Measurements included the attenuation coefficient in tissue attenuation imaging (TAI) and the scatter-distribution coefficient in tissue scatter-distribution imaging (TSI). The correlation between QUS and MRI-PDFF was evaluated. The diagnostic capabilities of QUS, conventional B-mode US, and their combined models for detecting hepatic fat content of \u22655% (MRI-PDFF \u22655%) and \u226510% (MRI-PDFF \u226510%) were compared by analyzing the areas under the receiver operating characteristic curves. Additionally, clinical risk factors influencing the diagnostic performance of QUS were identified using multivariate linear regression analyses.Results: TAI and TSI were strongly correlated with MRI-PDFF (r=0.759 and r=0.802, respectively; both P&amp;lt;0.001) and demonstrated good diagnostic performance in detecting and grading hepatic steatosis. The combination of QUS and B-mode US resulted in the highest areas under the ROC curve (AUCs) (0.947 and 0.975 for detecting hepatic fat content of \u22655% and \u226510%, respectively; both P&amp;lt;0.05), compared to TAI, TSI, or B-mode US alone (AUCs: 0.887, 0.910, 0.878 for \u22655% and 0.951, 0.922, 0.875 for \u226510%, respectively). The independent determinants of QUS included skinliver capsule distance (\u03b2=7.134), hepatic fibrosis (\u03b2=4.808), alanine aminotransferase (\u03b2=0.202), triglyceride levels (\u03b2=0.027), and diabetes mellitus (\u03b2=3.710).Conclusion: QUS is a useful and effective screening tool for detecting and grading hepatic steatosis during health checkups.<\/jats:p>","DOI":"10.14366\/usg.24040","type":"journal-article","created":{"date-parts":[[2024,5,29]],"date-time":"2024-05-29T14:56:35Z","timestamp":1716994595000},"page":"250-262","update-policy":"https:\/\/doi.org\/10.14366\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Diagnostic
