MRA
Magnetic resonance angiography (MRA) evaluates blood flow, or detects brain aneurysms or blood vessel abnormalities. It is used to visualize renal, carotid and vertebral arteries, or examine the aorta for aneurysm.
Frequently Asked Questions:
How long does the exam last?
Most MRAs last anywhere from 45 minutes to two hours, depending on the exam. It is very important that you remain absolutely still during the entire exam.
Is there any preparation involved?
There is no preparation needed for an MRA.
Why is MRA useful?
It provides a high quality tool for the radiologist to make a diagnosis of vessel disease. It shows abnormalities, such as stenosis (narrowing of a vessel) or aneurysm. It is a safe alternative to angiography, which is a surgical way to examine the blood vessels using iodine contrast.
