New version of CT/MRI LI-RADS released by ACR

By Staff News Brief

A new version of CT/MRI LI-RADS® (v2018) has been released by the Liver Imaging Reporting and Data System Steering Committee of the American College of Radiology (ACR). This new version is now integrated into the American Association for the Study of Liver Diseases (AASLD) 2018 hepatocellular carcinoma clinical practice guideline.

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 stated in a press release that integration is a major achievement in the LI-RADS mission and long-term vision to unify hepatocellular carcinoma (HCC) diagnostic imaging criteria.

“By implementing two minor changes to CT/MRI LI-RADS, we were able to unify LI-RADS with AASLD,” said Claude B. Sirlin, MD, chair of the LI-RADS Steering Committee. “Harmonizing these two guidance systems for liver imaging will further reduce imaging interpretation variability and errors, enhance communication with referring clinicians, enable the collection of standardized data and ultimately yield better patient outcomes.”

The updated LI-RADS CT/MRI v2018 Core is now available for download on www.acr.org.
