[Standardized screening and early imaging diagnosis strategies for hepatocellular carcinoma].

Standardized hepatocellular carcinoma (HCC) screening is very important for early diagnosis. Chinese and international HCC clinical guidelines recommend regular ultrasound screening for high-risk patients. Noninvasive dynamic enhanced imaging technology should be selected for the positive screenin population to get the further diagnosis, including contrast-enhanced ultrasound (CEUS), dynamic contrast-enhanced CT, dynamic contrast-enhanced MRI and Gd-EOB-DTPA enhanced MRI (EOB MRI). In clinical practice, early diagnose of HCC relies on accurate identification and stratification of high-risk patients, and systematic approach based on dynamic contrast-enhanced imaging.
