MR Angiography

What is MR Angiography?

Magnetic resonance angiography (MRA) is a specialized MRI imaging technique that is used to evaluate blood vessels and their flow. Commonly, an MR angiogram is ordered to evaluate arteries for blockages, clots, or plaque buildup.

What Are The Benefits Of MR Angiography?

An MRA imaging study has been shown to be very accurate when looking at the overall state of the blood vessels in comparison to a traditional MRI scan. An MR angiogram is a noninvasive imaging study that doesn’t exposure you to any amount of radiation. In comparison, A computed tomography angiogram (CTA) does involve small amounts of radiation.

What Are The Types Of MR Angiograms?

There are various forms of MRA imaging studies based upon which blood vessels are being viewed. Certain diagnostic imaging centers require contrast material to be used during the study. At Larchmont Medical Imaging, our team of medical professionals can carry out any MR angiogram with or without contrast. The ability to perform these studies without contrast is very helpful when working with patients who have a history of kidney, blood pressure, or insulin conditions.

• Aorta MRA – Examines the main aorta artery in the chest and abdomen to rule out aneurysms.
• Brain MRA – Examines areas of the brain for aneurysms or blockages of the arteries.
• Carotid MRA – Assess the carotid arteries to look for blockages that may cause a medical emergency.
• Leg MRA – Examines the arteries in the legs for blockages that may cause unexplainable leg pain (claudication).
• Renal MRA – Assesses the renal arteries to check for blockages that can increase the likelihood of kidney failure or hypertension.

How Do I Prepare For An MR Angiogram?

Most MRA studies do not require any preparation. If you are scheduled for an MRA of the abdomen, we will ask you to refrain from eating for several hours before the test.

Larchmont Medical Imaging asks you to complete a screening form to check for any metallic implants or pacemakers that may not be safe in an MRI machine. It is best to wear clothing that has no metal objects attached. If necessary, we may ask you to change into a gown so that the pictures aren’t degraded by any metal in your clothing. Our MRA imaging equipment has fast scan technology that allows imaging studies to be completed in 15 – 2o minutes. After the test, one of our subspecialized radiologists will review the images and send a report to your doctor.
