Figure 14b.

Double contrast-enhanced MR imaging appearance of confluent fibrosis with perivascular sparing in a man with alcohol-induced cirrhosis. Axial double contrast-enhanced (SPIO plus gadolinium) 2D gradient-echo images (140/6, flip angle = 70°), obtained at 1.5 T and displayed from superior (a) to inferior (d), show several areas of hyperintense confluent fibrosis (black arrows) in the liver. There are halos of low signal intensity surrounding many vessels (straight white arrow in a–c), a finding suggestive of perivascular sparing. Note the pseudotumoral hypertrophy of portions of the right and left lobes (curved arrows in c and d).
