From: Ten-year follow-up of renal adenomatosis with magnetic resonance imaging: a case report
Abdominal MRI with contrast enhancement performed in January 2010. a On axial fat-saturated T2-weighted images, papillary adenomas present as well-defined hypointense nodules (arrow and arrowhead) in the bilateral renal parenchyma. b, c Papillary adenomas present high signal intensity (arrow and arrowhead) on axial diffusion-weighted (b-value: 800) images and low signal intensity (arrow and arrowhead) on the corresponding apparent diffusion coefficient maps, suggesting diffusion restriction. d, e, f On axial dynamic contrast-enhanced T1-weighted images with fat suppression, papillary adenomas present isointensity in the renal parenchyma on unenhanced images and relatively poor contrast enhancement in the arterial and venous phases (arrow and arrowhead)
