Ultrasound Evaluation in Patients at Risk for Hepatocellular Carcinoma

Radiol Clin North Am. 2019 May;57(3):563-583. doi: 10.1016/j.rcl.2019.01.004. Epub 2019 Feb 14.

Abstract

In the context of chronic liver disease (CLD), sonographic features of hepatic steatosis, cirrhosis, and portal hypertension are discussed and examples are provided. The impact of CLD and hepatocellular carcinoma (HCC) is introduced, providing the rationale for a robust HCC screening and surveillance program for at-risk patients. The American College of Radiology Liver Imaging Reporting and Data System algorithms for screening and surveillance by ultrasound and for the definitive diagnosis of HCC by contrast-enhanced ultrasound are explained, with imaging examples provided. Contrast-enhanced ultrasound technique, limitations, and pitfalls also are introduced.

Keywords: Cirrhosis; Contrast-enhanced ultrasound; HCC; LI-RADS; Screening; Surveillance; Ultrasound.
