Limited added value of contrast-enhanced ultrasound over B-mode for the subtyping of hepatocellular adenomas

Purpose To compare the features of hepatocellular adenoma subtypes (HCAs) in B-mode and contrast-enhanced ultrasound (CEUS). Method Thirty-three patients (31 women [94 %] and two men [6%], median age [Q1–Q3] 43.5 years old [35−51]) with 44 pathologically proven and subtyped HCAs (including 29 inflammatory HCAs [I-HCA] and 15 HNF1-α inactivated HCAs [H-HCA]) who underwent CEUS were included. The features of HCA on B-mode and CEUS were...
