Hypointensity in the hepatobiliary phase is an important ancillary feature in the diagnosis of liver malignancies in the version 2018 of LI-RADS. In this study, Hypointensity in the hepatobiliary phase was used as the major features to explore the effect of hepatobiliary hypointensity on the diagnosis performance of LI-RADS in small hepatocellular carcinoma (sHCC). Our results indicated that the sensitivity of diagnosing sHCC can be significantly improved without affecting the specificity of diagnosing sHCC when Hypointensity in the hepatobiliary phase was used as the major features for classification of LR-3,LR-4.
