Fig. 6D —64-year-old man with surgically proven 12-mm hypervascular
hepatocellular carcinoma (HCC) and cirrhosis due to type B viral hepatitis.
Equilibrium phase spoiled gradient-recalled echo axial image (155/1.5)
obtained with centric k-space reordering and for which central k-space lines
were filled 181 seconds after arrival of contrast medium in abdominal aorta
shows almost no abnormal imaging findings for HCC. Ringlike coronal
enhancement in B is crucial in differential diagnosis between
hypervascular HCC and early enhancing pseudolesion, because equilibrium phase
image shows no abnormal imaging findings such as tumor washout or delayed
enhancement of fibrous pseudocapsules.
