A 71-year-old male with hepatocellular carcinoma (HCC). a The T2*-weighted image shows the tumor without a peritumoral hypointense rim. b This lesion was evaluated as grade 0 for peritumoral iron deposition and grade 0 for iron deposition in the background liver in a semiquantitative method. In addition, the mean optical density of this lesion was measured as 6168.5 for peritumoral iron deposition and 5145.7 for iron deposition in the background liver in a quantitative histopathological method.
