Fig. 1B. Hypervascular hepatocellular carcinoma with rapid central washout
and peritumoral coronal enhancement in 70-year-old man. First- to sixth-phase
images obtained with multiarterial phase contrast-enhanced dynamic MRI of
whole liver. Hypervascular hepatocellular carcinoma starts to show early
enhancement in second phase (arrow, B). Lesion is more clearly
seen in third phase (C) and then shows rapid central washout and
peritumoral coronal enhancement in fifth (E) and sixth phases
(arrow, F). Segmental enhancement in right lobe caused by
arterioportal shunt is also seen. No lesion is seen in this area.
