Fig. 2B. —54-year-old man with arterial hypertension (185 over 95 mm Hg) and suspected renal artery stenosis. Three-dimensional anteroposterior fast low-angle shot MR angiogram (3.8/1.49 [TR/TE], 25° flip angle, 10-sec acquisition time, 1.5-mm partition thickness) of first measurement after power injection of contrast material followed by saline solution reveals significant stenosis (solid arrow) of right renal artery, which was slightly overestimated at contrast-enhanced MR angiography (mean value of all four observers was 68.3%). Degree of stenosis was confirmed on additional views (not shown). Note no stenosis in left renal artery (mean value of all four observers was 0%). Also note aneurysmal dilatation of suprarenal aorta (open arrow).
