Core Tip

Core tip: Hepatocellular carcinoma (HCC) usually develops in the setting of chronic liver disease. Imaging criteria for HCC diagnosis rely on hemodynamic features, however, imaging diagnostic performance drops considerably for small (< 20 mm) nodules because of their tendency to exhibit atypical enhancement patterns. In order to improve accuracy in these non-typical lesions, the use of ancillary features has been incorporated into clinical reports, especially in Liver Imaging Reporting and Data System. In this paper, ancillary imaging features will be reviewed and illustrated.
