Fig. 2

MRI examination of a 33-year-old female; all the images are in the axial plane. Fig. a and b present slightly hypointense FNH in segment IV of the liver (arrow) on T2- and T1-weighted images. Central scar (small arrow) is hyperintense on T2-weighted images (Fig a). In hepatic arterial phase, the lobulated lesion presents strong enhancement (Fig. c). In portal venous phase (Fig. d) and equilibrium phase (Fig. e) the lesion stays hyperintense, however, the enhancement is weaker than in hepatic arterial phase. In hepatobiliary phase (Fig. f) the lesion is hyperintense and enhancement of the scar is visible (arrow)
