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:
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.

In collaboration with the LI-RADS® Steering Committee, the Ultrasound or US LI-RADS® workgroup developed and refined a standardized system (ACR US LI-RADS® or US LI-RADS®) for technique, interpretation, reporting, and data collection for screening and surveillance ultrasound exams in patients at risk for developing HCC.

The ACR also announces the formation of a new working group:
The Treatment Response (TR) LI-RADS Working Group, Chaired by Dr. Richard K. Do, from Memorial Sloan Kettering Cancer Center.
In collaboration with the LI-RADS Steering Committee, the LI-RADS TR WG will develop and refine a standardized system for the interpretation, reporting and data collection for treatment response assessment in patients who undergo liver directed treatments for known or suspected HCC. The system will be called ACR TR LI-RADS, or TR LI-RADS for short. It will include a lexicon of controlled terminology, an illustrative atlas, reporting guidelines, and educational material. It will be updated as experience accrues, as knowledge add technology advance, and in response to user feedback
Initial release is anticipated in 2017.
