Introduction and Objective
The Liver Imaging Reporting and Data System (LIRADS) was created to standardize the reporting and data collection of MR imaging for hepatocellular carcinoma (HCC) in high risk patients. The major categories for LIRADS have the following descriptors:
LI-RADS 1 = Definitely benign
LI-RADS 2 = Probably benign
LI-RADS 3 = Intermediate probability for HCC
LI-RADS 4 = Probably HCC
LI-RADS 5 = Definitely HCC
LI-RADS 5V = Definitely HCC with tumor in vein
LI-RADS M = Probable malignancy, not specific for HCC
LI-RADS T = Treated Observation
However, there is a paucity of quantitative evidence for the progression of LIRADS 2, 3 and 4, (hereafter defined as intermediate LIRADS categories) to LIRADS 5. Our objective was to investigate the conversion of intermediate LIRADS categories to definite hepatocellular carcinoma (LIRADS 5) to help inform management decisions regarding treatment and better stratify imaging follow up for high-risk patients with intermediate LIRADS categories.
