Cardiac Magnetic Resonance Imaging (MRI)

Generally, an cardiac MRI follows this process:

1. Remove any clothing jewelry, eyeglasses, hearing aids, hairpins, removable dental work, or other objects that may interfere with the MRI.
2. If you are asked to remove clothing, you will be given a gown to wear.
3. If you are to have a MRI done with contrast, you will have an intravenous (IV) line in the hand or arm to inject the contrast dye.
4. You will lie on a scan table that slides into a large circular opening of the scanning machine. You will lie down for 30 to 60 minutes.
5. It’s important to remain very still during the test. Any movement could affect the quality of the scan.
6. You may be told to hold your breath, or to not breathe, for a few seconds. You will then be told when you can breathe.
7. You will be given earplugs or a headset to wear to help block out the noise from the scanner. You may be able to listen to music.
8. During the scanning process, a clicking noise will sound as the magnetic field is created and pulses of radio waves are sent from the scanner.
9. If contrast dye is used you may feel effects as the dye is injected into the IV line that includes coolness or discomfort that should only last a few seconds.
10. If you have metal fillings in your teeth, you may feel some slight tingling in your teeth during the test.
11. The MRI itself causes no pain. But, having to lie still for so long might be uncomfortable.
