Fig. 2. Pretreatment MR image obtained in 67-year-old man with advanced
hepatocellular carcinoma. Axial contrast-enhanced dynamic 2D turbo fast
low-angle shot MR image acquired during arterial phase shows 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 (not shown)
obtained during treatment revealed no morphologic change in any hepatic tumors
but increase in all tumor perfusion parameters, compatible with clinical
disease progression evidenced by elevated serum
-fetoprotein level.
