Based on the CEUS LI-RADS recommendations of the American College of Radiology [16].

CEUS LR-M criteria: any of following: rim APHE or early (<60 seconds) washout or marked washout.

CEUS, contrast-enhanced ultrasonography; LI-RADS, Liver Imaging Reporting and Data System; APHE, arterial phase hyperenhancement.

^a)Rim APHE indicates CEUS LR-M.

^b)Peripheral discontinuous globular indicates hemangioma (CEUS LR-1).
