Nodular regenerative hyperplasia (NRH) of the liver is not common, and no MR imaging of this condition has been reported. We describe a case of NRH with findings of US, CT, MR and angiography. US showed hypoechoic nodules; spiral CT showed enhancing nodules during the arterial phase; MR showed no detectable masses on T1 and T2-weighted images, and angiography showed hypervascular masses on arterial phases.
