Figure 3d: Transverse MR images show solitary HCC in 71-year-old obese man with type 2 diabetes. (a) T2-weighted turbo spin-echo image (3250/110) shows a mass (arrow) with well-defined margins and a regular surface in the right posterior segment. The mass is hyperintense to liver. Note the compression of the right hepatic vein (arrowhead). (b) Unenhanced T1-weighted gradient-recalled-echo out-of-phase image (145/1.8, 80° flip angle) shows that the tumor (arrow) is isointense to adjacent liver. (c) Contrast-enhanced fat-saturated T1-weighted image (160/4.9, 80° flip angle) obtained during hepatic arterial phase demonstrates heterogeneous enhancement of the tumor (arrow). (d) Image obtained during portal venous phase shows that the tumor (white arrow) demonstrates persistent hyperintensity compared with adjacent liver parenchyma. Note also the perfusion abnormality (black arrow) at the periphery of the tumor. (e) Image obtained during delayed phase shows that the tumor (arrow) becomes isointense to adjacent liver parenchyma. Note the hyperintense rim, which corresponds to the tumoral capsule.
