Fig. 3 MRI shows a well-defined lesion in liver segment IV. Lesion is moderately hyperintense on T2 HASTE sequence (a) and shows restriction of diffusion (b). In-phase GRE (c) and out-of-phase GRE (d) sequences were performed and no drop of signal was noted in the lesion.

Fig. 4 MRI of the liver with hepatobiliary-specific contrast agent. (a) Lesion is hypointense on T1 VIBE pre-contrast mage. (b) Lesion shows intense homogeneous enhancement in the arterial phase. (c) Lesion is hypointense in comparison with liver parenchyma in venous and in hepatospecific phase (d).
