MR Imaging of Hepatocellular Adenomas and Differential Diagnosis Dilemma
Figure 8
Large regenerative hyperplasia. (a) Axial T2w image. In S VII slightly hyperintense nodule (arrow); in SIV moderate hypointense lesion (arrowhead). (b-c) T1w in- and out-phased images. Due to significant steatosis of hepatic parenchyma after chemotherapy, many other hypointense lesions appear in out-phased sequence. (d–f) In dynamic evaluation after Gd-BOPTA administration the nodules appear significantly hypervascular in arterial phase (d) and tend to be isointense in portal and equilibrium phases. (g) Hepatobiliary phase image after 1 hour. Nodules are hyperintense.
