Gadoxetic acid-enhanced magnetic resonance imaging can predict the pathologic stage of solitary hepatocellular carcinoma

Figure 3 Images in a 64-year-old man with a solitary hepatocellular carcinoma (tumor size 5. 5 cm) in segment VIII. A and B: Axial view of T2- and T1-weighted magnetic resonance images with fat suppression before administration of gadolinium ethoxybenzyl diethylene-triaminepentaacetic acid; C: Arterial phase and D: Portal venous phase showing hyperenhancing mass in segment VIII with partial washout appearance and corona enhancement (arrow); E: Subtracted images of the portal venous phase with more obvious corona enhancement; F: Hepatobiliary phase, T1-weighted three-dimensional gradient-echo magnetic resonance image (axial view) with fat suppression. The obvious flame-like peritumoral hypointensity (arrow) is noted. This tumor was identified postoperatively as a pT2 hepatocellular carcinoma owing to its microvascular invasion.
