A renal angiography is a type of imaging test that examines the blood vessels in your kidneys. It can be used by your healthcare provider to examine blood vessel ballooning (aneurysm), blood vessel narrowing (stenosis), or blood vessel blockages. He or she can also assess how well blood flows to your kidneys.
The radiologist injects a contrast dye into the artery that leads to the kidney for the test. The dye is then observed as it flows through the blood vessels in the kidneys using X-ray images. A renal angiogram may be required to assist your healthcare provider in detecting problems in your kidney's blood vessels. These issues may include: Blood vessel enlargement (aneurysm)
Blood vessel constriction (stenosis), A blood vessel spasm (vasospasm), faulty connection between arteries and veins (arteriovenous malformation), Clot in the blood (thrombosis)
