Information for Patients: Commonly Used Diagnostic Tests: MRA
Medical Description Why is it done? The test is the most accurate noninvasive method for finding out if there are blockages to the arteries of the kidneys (renal arteries). It also shows if there is plaque from atherosclerosis (high cholesterol) in other arteries. What will it show? The test shows pictures of the blood flow in the arteries. How is it done? Magnetic resonance works by beaming a very high magnetic field through the body, which makes body tissues show up on x-rays. You have to lie in a metal tube which contains the magnet for the test to be done. You also have an injection of a substance called gadolinium into a vein to make the arteries show up better. Are there any risks? Some people find it uncomfortable to lie in the tube. If you have any metallic objects implanted in your body (such as a heart pacemaker) you should check with your doctor. There are no side effects from the gadolinium injection. Practical Details Where do I go to have the test? Presbyterian Hospital Building -- 3 rd Fl. (PH-3) located at 622 West 168 th Street How Do I Prepare for the Test? No preparation needed How long will it take? Approximately 1½ hrs. How much will it cost? $950.00 How much will I have to pay? If you have Medicare or Medicaid the cost is usually covered in full. If you have other forms of insurance you will need to check with your insurance if the cost is covered.
