Magnetic Resonance Angiography (MRA) uses radio waves delivered while the patient is placed in a magnetic field to create images of arteries and veins. MRA is usually performed with a special gadolinium based contrast to make the arteries and veins bright, much like CTA. Some MRA studies can be performed without contrast and do not even require an IV.

MRA is a particularly powerful vascular imaging modality in that it is extremely safe, noninvasive and does not use radiation to obtain images. Non-contrast MRA can be used safely in patients who have impaired kidney function. MRA takes longer than CTA, but has the advantage of not being affected by the calcium that can develop in the vessel walls of patients with atherosclerosis.

Your doctor can help determine which tests are right for you in order to evaluate blockages of the arteries or veins. The vascular laboratories within the Inova Heart and Vascular Institute provide all of the latest imaging techniques to diagnose and ultimately treat vascular diseases.
