Introduction to the Liver Imaging Reporting and Data System (LI-RADS) for hepatocellular carcinoma

The Liver Imaging Reporting And Data System (LI-RADS) was created with the support of the American College of Radiology (ACR) to standardize the acquisition, interpretation, reporting and data collection for imaging examinations in patients at risk for hepatocellular carcinoma (HCC). A comprehensive and rigorous system developed by radiologists, hepatologists, pathologists, and surgeons, LI-RADS addresses a wide range of imaging contexts. Currently, four algorithms are available publicly on the ACR website: ultrasound for HCC surveillance, computed tomography (CT) and magnetic resonance imaging (MRI) for HCC diagnosis and tumor staging, contrast-enhanced ultrasound (CEUS) for HCC diagnosis, and CT/MRI for treatment response assessment.
