Magnetic resonance arteriography and venography are minimally invasive imaging techniques that use a scanner which projects magnetic field radio waves in order to create images of the arteries and veins. These images assist in diagnosing vascular abnormalities without the use of X-ray technology; no radiation is required.

How to Prepare for an MRA/MRV scan

  • If you have any allergies, are taking medication, blood thinners, have claustrophobia, or are pregnant please notify the staff.
  • Remove jewelry and other metal accessories.
  • You will be assisted by a technologist who is in a connected room during the procedure. They can communicate with you via microphone.
  • You’ll be lying on a radiographic table throughout the procedure. If you experience discomfort, you may ask for a pillow or blanket. The staff can also provide headphones which will play music during the scan.
  • If the scan requires contrast dye, you should not eat 4-6 hours before the procedure. The dye is injected through an IV into your veins. You may feel a warm sensation, but should not feel pain.
  • Coils (antennas used to direct the energy) are placed around the area that needs imaging.

What to Expect

  • The bed rises and moves you through the tunnel-shaped machine. As images are taken, the machine makes a series of bumping and humming noises.
  • You may be asked to hold your breath in order to remain still during the scan.

What to Expect after an MRA/MRV scan

  • You will wait on the table until your technologist confirms that the images are successful. You can leave afterwards, and return to your regular activities.
  • Your interventional radiologist will discuss the results with your primary care or referring physician, who will consult with you about the next steps in your treatment process.
