[Comparison between pathological findings and MR diffusion-weighted imaging in primary hepatocellular carcinoma after transcatheter arterial chemoembolization].

Objective: To explore the pathological basis of diffusion-weighted imaging (DWI) findings in hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).

Methods: DWI was performed in 15 patients with HCC treated by TACE within 24 - 48 hours before II-phase operation. The DWI findings of the liver lesions were analyzed and correlated with pathological findings including macroscopic observation, HE staining and immunohistochemical staining for bFGF.
