The Liver Imaging Reporting and Data System (LI-RADS) was created to standardize the reporting and data collection of CT and MR imaging for hepatocellular carcinoma (HCC). This method of categorizing liver findings for patients with cirrhosis or other risk factors for developing HCC allows the radiology community to:
The LI-RADS Committee has approved an updated CT/MRI diagnostic algorithm, a new treatment response assessment algorithm, basic management guidance, basic reporting guidance, key definitions, core supporting material, and FAQs.

ACR CEUS LI-RADS, or CEUS LI-RADS for short, is a standardized system for technique, interpretation, reporting, and data collection for contrast-enhanced ultrasound (CEUS) exams in patients at risk for developing HCC. The system currently includes a lexicon of controlled terminology, schematic illustrations, and a categorization algorithm. A complete illustrative atlas, reporting guidelines, and educational material are in development. CEUS LI-RADS will be updated as experience accrues, as knowledge add technology advance, and in response to user feedback.
ACR CEUS LI-RADS was developed by a working group of national and international experts. The group is Chaired by Dr. Yuko Kono, MD, of the University of California, San Diego. Members include radiologists and hepatologists from the United States, Canada, Europe, and Asia. The group was convened in April 2014. Beta versions of the CEUS LI-RADS algorithm were presented at national and international conferences in 2015 and 2016. Feedback was solicited. Based on the feedback and iterative consensus, the working group refined and in 5-21-16 finalized the CEUS LI-RADS algorithm. The algorithm was officially approved by the ACR LI-RADS Steering Committee on 6-24-16 and submitted to the ACR for public release on 6-24-16.
