Radiology Exam: Magnetic Resonance Angiography (MRA)

MRA is a diagnostic radiology exam that uses radio waves, a magnetic field and a computer to produce images of inside the body. MRA is used to evaluate blood flow and look for narrowing or blockages of blood vessels to organs or other areas of the body.

To create clearer images of the blood vessels, an MRA exam will often use a contrast agent called gadolinium inserted through an IV line. MRA exams do not use radiation.
MRA: What You Need to KnowMRA exam

  • MRA is a type of MRI that looks specifically at blood vessels in the body.
  • MRA is often used to examine the blood vessels in the brain, neck, abdomen, heart, chest, arms and legs.
  • A doctor may order an MRA exam to look for blood vessel diseases and conditions such as an aneurysm, atherosclerosis, stroke, pulmonary embolism, coronary heart disease, or other abnormalities of the arteries and veins.
  • Because an MRA exam produces a strong magnetic environment, it is very important that you tell your doctor about any metal or implantable device anywhere within your body, including a pacemaker, insulin pump or metal pins.
