The American College of Radiology (ACR) has released a new version of its Liver Imaging Reporting and Data System (LI-RADS): CT/MRI LI-RADS v2018.

The new version of CT/MRI LI-RADS features two minor changes that enable it to be integrated into the American Association for the Study of Liver Diseases (AASLD) 2018 hepatocellular carcinoma (HCC) clinical practice guidance, according to the ACR.

LI-RADS v2018 revises the definition of the LI-RADS major feature threshold growth and revises one LI-RADS category 5 criterion (10-19 mm + arterial phase hyperenhancement + "washout" = LR-5). The ACR said it intends to return now to a three- to four-year update cycle for CT/MRI LI-RADS, with the next major comprehensive update anticipated in 2021.
