American College of Radiology (ACR) Liver Imaging Reporting and Data System (LI-RADS)
Definitions
ACR LI-RADS was introduced in 2011 to standardize performance, interpretation, and reporting of focal liver observation in patients at risk for developing hepatocellular carcinoma (HCC)
CEUS LI-RADS was introduced in 2016, updated in 2017, and is imaging technique that uses intravenously administered microbubbles to evaluate enhancement characteristics of focal liver observations visible on US in patients at risk for developing HCC
