Fig. 4. —Pretreatment MR image of 77-year-old man with advanced hepatocellular carcinoma. Coronal contrast-enhanced dynamic turbo fast low-angle shot MR image obtained during late arterial phase shows multiple hyperintense tumors in right lobe of liver. Tumoral region of interest with maximal enhancement (circle with arrow) and parenchymal region of interest (circle with arrowhead) are depicted. Follow-up MR image obtained during treatment (not shown) showed no morphologic change in any of liver tumors. However, reduction of all tumor perfusion parameters was noted, corresponding to clinically stable disease.
