ABSTRACT
PURPOSE: We performed dynamic MR imaging using GdDTPA to find characteristic enhancement pattern of hepatic hemangioma distinguishing from hepatocellular carcinoma. METHODS AND MATERIALS: 28 hepatic hemangiomas and 10 hepatocellular carcinomas were evaluated. Serial dynamic scans after Gd-DTPA(0.1mmol/kg) intravenous injection were obtained by using 0.5T machine and analyzed contrast-to-noise ratio(CNR) of the lesion and enhancement pattern on each scan. RESULTS: Hepatic hemangiomas had positive CNR from 1-2 minute images, and revealed typical "fill-in phenomenon" on early phase with prolonged enhancement in 26 cases(92.8%), and early homogeneous enhancement with isointensity on delayed phase in 2 cases(7.2%) of small hemangiome~ Hepatocellular carcinomas revealed inhomogeneous enhancement with hypointensity on delayed phase in 10 cases(100%) and 3 cases (30%) of capsular enhancement. CONCLUSION: Hepatic hemangioma can be easily distinguished from hepatocellular carcinoma by using Gd DTPA enhanced dynamic MR imaging according to its typical enhancement pattern of "fill-in phenomenon" and prolonged enhancement.
