Diagnosis of Renal Vascular Disease
Your healthcare provider will review your medical history and do a physical exam. Other tests may include:

Arteriogram (or angiogram). This is an X-ray image of the blood vessels used to check for aneurysm, narrowing, or blockages. A dye (contrast) is injected through a thin, flexible tube placed in an artery. This dye makes the blood vessels visible on X-ray.

Duplex ultrasound. This test is done to check blood flow and the structure of the renal veins and arteries. The term "duplex" refers to the fact that 2 modes of ultrasound are used. The first takes an image of the renal artery being studied. The second mode checks the blood flow.

Renography. This test is used to check the function and structure of the kidneys. It is a type of nuclear radiology procedure. This means that a tiny amount of a radioactive substance is used during the test to help view the kidneys.

Magnetic resonance angiography (MRA). This test uses a combination of magnetic resonance imaging (MRI) technology and intravenous (IV) contrast dye to see blood vessels. Contrast dye causes blood vessels to appear solid on the MRI image. This lets the healthcare provider see the blood vessels.
