A 68-year-old male with hepatocellular carcinoma (HCC). a A T2*-weighted image shows the tumor with a peritumoral hypointense rim (white arrows). b This lesion was evaluated as grade 3 for peritumoral iron deposition (black arrows) and grade 1 for iron deposition in the background liver in a semiquantitative histopathological method. In addition, the mean optical density of this lesion was measured as 34,321.7 for peritumoral iron deposition and 19,475.5 for iron deposition in the background liver in a quantitative histopathological method.
