Research Abstract

(1)Cholangiolocellular carcinoma has the dual imaging characteristics of hepatocellular carcinoma and cholangiocarcinoma. (2)Gadoxetic acid-enhanced MRI was found useful for differentiating intrahepatic cholangiocarcioma and poorly differentiated hepatocellular carcinoma, especially during the dynamic late phase.(3)The frequency of fatty change in pHCC, as well as in wHCC, is significantly higher than that of mHCC. One possible mechanism of it is intratumoral decreased arterial flow
