Figure 4. 65-year-old male, hepatitis C cirrhosis, arterial phase MR images. Pretreatment image shows a 2.1 LR-5 observation with APHE and washout (not shown), consistent with HCC. Three- and seven months follow-up image after Y-90 shows peripheral APHE along the treatment zone (arrows), most likely related to hyperemic response, progressive tumor response with granulation tissue and fibrosis development.
