MRA
One type of specialty MRI (magnetic resonance imaging) that 611 MRI provides is called an MRA. MRA stands for magnetic resonance angiography. Angiography, also known as arteriography, is an imaging method used to photograph the blood vessels.
MRA is most commonly used to capture images of blood vessels in the neck, kidneys, and brain. MRA angiograms may or may not require contrast depending on the body part being scanned. Once the scan is completed, our radiologists will review the scan.
MRA can find issues that reduce blood flow, including:
- Calcium deposits, blood clots, or aneurysms
- Vessel abnormalities of the brain
- Stenosis (narrowing of the blood vessels)
- Aortic narrowing
MRA can also help determine how much blood is supplying cancerous tumors, evaluating patients exhibiting signs of stroke, and diagnose potentially disruptive lesions in the arteries.
How do I prepare for an MRA?
We advise you to dress in clothes that are metal-free (no zippers, brass buttons, etc) for your exam, but we can also provide you with a dressing gown. Individual dressing rooms are available for your privacy and all metal objects, including coins and watches, will be kept safely in a locker.
You will be notified if you require special preparations prior to your exam.
What if I am claustrophobic?
If you are claustrophobic, you must request a prescription for a sedative from your physician for you to pick up at your local pharmacy. Please also let our staff know that you will be taking a sedative as you will need to have a family member drive you to your appointment.
