Important Things to Know About MRA
Magnetic resonance angiography (MRA) is a type of magnetic resonance imaging (MRI). An MRA provides detailed images of blood vessels without the use of catheters or surgery. Like MRI, MRA is safe and painless.
During an MRA scan, you lie on a cushioned table that moves into the scanner. An injected contrast agent may be used to make blood vessels more visible on your images. These contrast agents rarely cause allergic reactions
