Figure 3c: FMD of right medial renal artery. (a) Nonselective anteroposterior aortogram shows long stenosis (arrow) in medial part of the right renal artery. (b) Coronal maximum intensity projection and (c) volume-rendered image, both of which were obtained at contrast-enhanced MR angiography (5.2/1.5, 40° flip angle, and 0.78 x 0.78 x 1.5-mm reconstructed voxel), show lesion with overestimation of stenosis.
