How to Get Prepared for Magnetic Resonance Angiography

Magnetic Resonance Angiography, also known as magnetic resonance angiogram or MRA is a kind of magnetic resonance imaging (MRI) scan that is done with the help of magnetic field and pulses of radio wave energy so that the image of blood vessels inside the body can be made visible. This MRI is done to look explicitly at the blood vessels of the body. There are a number of cases in which the results obtained through Magnetic resonance angiography are much better and efficient then those obtained through X-ray, ultrasound, or computed tomography (CT) scan.

An MRA is helpful in finding out the condition of the blood vessels and also the blood flow and it is also used to detect the problems that are related to blood vessels that may be the cause of interruption and reduction in the blood flow. The reason behind conducting this test is to examine the blood vessels that go to the brain, kidney and legs. The results that are obtained through Magnetic resonance angiography can be saved for further examination and study about the problem.

Magnetic Resonance Angiography – Why is This Test Done

This test is mainly performed to find out the following things –

  • You need to go for MRA when there is a bulge (aneurysm) or a clot, or you notice increase of fats and calcium deposits in the blood vessels of your body that mainly goes to the brain.
  • If there is Aneurysm or tear in the aorta that is the blood carrier and is used to pump out the blood from the heart to the different parts of the body.
  • When the blood vessels that goes to heart, kidneys, lungs and legs becomes thin and starts narrowing.

Getting prepared for Magnetic resonance angiography

There are certain precautions that you need to take while going for an MRI test for you. This is to ensure complete safety and prominent results. Below is the list of a few necessary things that you need to tell to your doctor before appearing for the test. Have a look at these:

  • If you are pregnant or experiencing pregnancy symptoms

  3. If you asked to have any blood tests avoid the intake of alcoholic drinks, caffeinated beverages, cigarette, tobacco or other such products for at least two hours before the tests
  4. You should not take iron supplements on the day you are having your MRA (Magnetic resonance angiography)

Most of the preparations details for an MRA test have been shared with you still it is suggested to have a word with the doctor before going for it. It would be good for you have all the doubts clear before going for the test so as to have the most appropriate results without any complications.
