Fig. 1 Axial phase-contrast magnetic resonance cineangiographic image of aorta (A) and renal arteries in 57-year-old man. Small segment of signal void (arrow) in proximal left renal artery corresponds to stenosis noted on conventional angiography (Fig. 2).

Fig. 2 Aortogram demonstrating left renal artery stenosis (arrow) and poststenotic dilatation in 57-year-old man. Stenosis was considered hemodynamically significant (80% diameter reduction).
