Abstract:
We assessed the magnetic resonance imaging (MRI) features of hepatic lobar atrophy. Two of us reviewed MRIs of the liver in eight patients with benign or malignant forms of lobar atrophy. All atrophic lobes showed low signal intensity on T1-weighted images and high signal intensity on T2-weighted images compared with the remainder of the liver, and all showed greater enhancement compared to the nonatrophic lobe. Atrophic lobes have suggestive MRI findings and are similar for both benign and malignant etiologies.
