A 57-year-old man with a hypovascular, hyperintense nodule on hepatocyte imaging of EOB-MRI (yellow arrows) (a, b). A nodule of 8-mm in size was demonstrated as slight hyperintensity on hepatocyte imaging (b) of the initial EOB-MRI examination. At this time, the nodule was not identified on the hepatic arterial-dominant phase imaging (a) because it did not show hypervascularity. On follow-up images of an EOB-MRI obtained 12 months after the initial examination, the nodule showed hypervascularity on hepatic arterial-dominant phase imaging (c). The nodule remained slightly hyperintense on hepatocyte imaging (d). On follow-up images of EOB-MRI obtained 17 months after the initial examination, the nodule with hypervascularity increased in size on hepatic arterial-dominant phase imaging (e) and hepatocyte imaging (f). The nodule showed no interval change of the high signal intensity on hepatocyte imaging (f).
