摘要
This retrospective study was conducted to investigate the diagnostic accuracy of ultrasound-derived fat fraction (UDFF) for grading hepatic steatosis using liver histology as the reference standard. Seventy-three patients with liver disease were assessed using UDFF and liver biopsy. Pearson’s test and the Bland–Altman plot were used to assess the correlation between UDFF and histological fat content in liver sections. The UDFF cutoff values for histologically proven steatosis grades were determined using the area under the receiver operating characteristic curve (AUROC). The median age of the patients was 66 (interquartile range 54–74) years, and 33 (45
