Magnetic Resonance Angiography (MRA)
This is a test using magnets and radio waves to build a 3D model of your body. Typically the procedure takes between 30 and 60 minutes, during which you will need to remain very still and follow breathing instructions. You will hear loud noises during the test which are the magnets turning on and off.
What do I need to know?
The test takes place inside the MRI magnet which resembles a tube. Patients with severe claustrophobia may need a sedative before the procedure. Because the test uses powerful magnets, patients with anuthing metallic in their body may be at risk for problems. You will be screened before the procedure to make sure that it is safe. Orthopedic hardware is not a problem but may interfere with images. Generally patients with spinal stimulators, pacemakers or defribrillators are not candidates for this test.
