To determine the value of MRE in the differential diagnosis of hepatocellular carcinoma and intrahepatic cholangiocarcinoma with 3.0-T MR scanner . The MRE were performed in 36 patients(26 hepatocellular carcinomas and 11 intrahepatic cholangiocarcinomas) by using 60-Hz mechanical waves and Spin echo echo planar sequence.Intrahepatic cholangiocarcinomas had significantly greater mean shear stiffness than hepatocellular carcinoma (9.08 ±2.13kPa vs 6.54 ±1.84kPa). They have statistically significant differences(p<0.01).MRE can help the differentiation of hepatocellular carcinoma and intrahepatic cholangiocarcinoma.
