Fig 1 A, Magnetic resonance angiography (MRA) demonstrates bilateral high-grade renal artery stenoses. B, Contrast arteriography in the same patient indicates <50% stenosis of the right renal artery and high-grade stenosis of the left renal artery. MRA overestimated the significance of the right renal artery lesion.

Fig 2 A, Magnetic resonance angiography indicates high-grade stenosis of the left renal artery. B, Selective contrast arteriography indicates a normal left renal artery.

Fig 3 A, Magnetic resonance angiography (MRA) indicates irregularities of the distal third of the right renal artery suggestive of fibromuscular dysplasia. B, Contrast arteriography of the same artery indicates an essentially normal right renal artery. C, A multiplanar reconstruction of the MRA indicates the lack of significant stenoses of the right renal artery.
