MR Angiography

Magnetic Resonance Angiography (MRA) is an MRI study of blood vessels. MRA utilizes advanced MRI technology to detect, diagnose, and aid in the treatment of vascular disorders or abnormalities in the head, neck, arms, legs and abdomen. MRA highlights the vessels through the use of gadolinium-based contrast (dye) material. This procedure is best performed on a high-field MRI scanner.

Exam preparation

A CDI representative will call you prior to your appointment to provide specific instructions, and review health and insurance information
Because of the magnetic field, you will be asked to wear metal-free clothing, or to change into a gown. You also will be asked to remove any metallic objects, such as jewelry, watches, and hair clips.
Inform your technologist of prior surgeries or metal implants, such as pacemakers or aneurysm clips.
Notify a member of CDI’s staff if you are nursing or if there is a chance you could be pregnant
Bring prior x-rays or scans with you to your exam, if instructed.
Please arrive 15 minutes early to verify your registration.

During the exam – what to expect

You will lie on a cushioned table and an imaging device called a “coil” will be placed around the area of the body to be scanned.
Once comfortably positioned, the table will move into the magnet opening.
As images are acquired, you hear “knocking” sounds for several minutes at a time. It is important to lie as still as possible during this part of the exam to ensure clear images.
If contrast material needs to be used, you will receive an I.V. in the hand or arm before you are moved inside the scanner.
Once the contrast, called gadolinium, is injected, you may feel a warm, flushed sensation, and experience a metallic taste in your mouth that lasts for about two minutes.
Additional pictures will be taken once the contrast is injected. Depending on the type of exam, you could be in the scanner anywhere from 10 minutes to one hour.

After the exam – what to expect

A radiologist who specializes in a specific area of the body will review your images (i.e., a neuroradiologist will review images of your brain).
The radiologist prepares a diagnostic report to share with your doctor.
Your doctor will consider this information in context of your overall care, and will talk with you about the results.
