Magnetic Resonance Angiography (MRA)
MRA is an Magnetic Resonance Imaging (MRI) study of the blood vessels. It utilizes magnetic resonance (MR) technology to detect, diagnose and guide the treatment of heart disorders, stroke and blood vessel diseases. MRA provides detailed images of blood vessels without a contrast medium given intravenously. However, gadolinium is often used to markedly improve the quality of the MR images of the vessels.
How is the Procedure Performed?
MRA provides detailed images of blood vessels without having to insert a catheter directly into an artery. There is no significant recovery time and cost is substantially less when compared to standard angiography. A very small amount of gadolinium based contrast medium may be injected — unlike catheter angiography which uses a large volume of iodine-based contrast. MR contrast is very safe and the risk of an allergic reaction is extremely low.
