Abstract

We studied the renal arteries prospectively in 16 patients with renal insufficiency using a combination of two-dimensional and three-dimensional time of flight magnetic resonance angiography (MRA). Results were compared with conventional angiography. All renal arteries were identified by MRA. Accuracy for classifying renal arteries into patent, moderately (30-70%) stenotic, severely (>70%) stenotic, or occluded was 91%. With regard to the presence or absence of severe occlusive disease (>70% stenosis or occlusion) the sensitivity was 100%, with a specificity of 93%.
