Abstract:
To improve standardization and consensus regarding interpreting,and reporting CT and MRI scans of the liver in patients with high-risk HCC,Liver Imaging Reporting and Data System (LI-RADS) was launched in 2011 and subsequently modified in 2013 and 2014,respectively.Major diagnostic imaging features for HCC are hyper-enhancement in the arterial phase,rapid dissection in the portal vein phase and balance phase,capsule presence and appearance,interval threshold tumor growth and tumor diameter.LI-RADS categorizes nodules recognized at CT or MRI as LR-1 (definitively benign),LI-RADS is a system of standardized criteria for interpreting liver CT and MR images of patients at risk of hepatocellular carcinoma in higher interobserver reliability and faster categorization while maintaining diagnostic accuracy.LR-2 (probably benign),LR-3 (intermediate probability of being HCC),LR-4 (probably HCC) and LR-5 (definitively HCC).According to diagnostic classification,different options for treatment recommendations are adopted by surgeons including continue standard surveillance,regular follow-up,alternative imaging method,multidisciplinary discussion,liver resection or transplantation.LI-RADS is a system of standardized criteria for interpreting liver CT and MR images of patients at risk of hepatocellular carcinoma in higher interobserver reliability and faster categorization while maintaining diagnostic accuracy.
