Group A was consisted of HCCs with dense lipiodol uptake (more than 90%) and group B with partial lipiodol uptake (between 50% and 90%). One HCC in group A had no T2WI, and one HCC in group B had no diffusion weighted images (b=0).
HCC, hepatocellular carcinoma; T2WI, T2-weighted images; T1WI, T1-weighted images; DWI, diffusion-weighted images; GE in, in-phase gradient-echo images; GE out, out-of-phase gradient-echo images.
