Fig. 4A. Hypervascular pseudolesion in 55-year-old man. First- to sixth-phase
images obtained with multiarterial phase contrast-enhanced dynamic MRI of
whole liver. Hypervascular pseudolesion starts to show early enhancement from
third phase (arrow, C). Lesion enhancement continues until
sixth phase (E). Lesion enhancement of hypervascular pseudolesion
appears later and lasts longer than that of hypervascular hepatocellular
carcinoma without rapid central washout shown in Figures
3A,
3B,
3C,
3D,
3E, and
3F. Rapid central washout and
coronal enhancement are not seen.
