Renal arteriography is used in polyarteritis nodosa and renal artery stenosis to demonstrate multiple aneurysms or stenoses. Because of the availability of procedures that do not require contrast material (eg, ultrasonography, MRI, and MRA) do not carry a risk of contrast nephrotoxicity, this test is less commonly used than it once was.
