MRA (Magnetic Resonance Angiography) is a specialized type of MRI exam used to obtain images of the arteries of the brain, carotid arteries, aorta, renal arteries and vessels of the extremities. MRA is used to detect problems with blood vessels that may be causing reduced blood flow.
An MRA exam will take about 30 minutes.
Your exam may require contrast material to be injected through an IV. In this case, an IV will be placed in your arm before the scan starts. You will be positioned on a cushioned table inside the MRI scanner. The scanner will make a drumming sound as it captures the images. You may listen to music to muffle this sound if you’d like. To ensure the best quality images, you will be asked to remain as still as possible during the exam.
Your images will be interpreted by one of our board-certified radiologists. The findings will be sent to your healthcare provider who will then contact you to discuss the results.
You may resume regular activities immediately after your exam.
