Magnetic Resonance Imaging
WHAT YOU NEED TO KNOW:
What do I need to know about magnetic resonance imaging (MRI)?
An MRI is a test that uses magnetic fields and radio waves to take pictures inside your body. An MRI is used to see blood vessels, tissue, muscles, and bones. It can also show organs, such as your heart, lungs, or liver. An MRI can help your healthcare provider diagnose or treat a medical condition. It does not use radiation.
How do I prepare for an MRI?
- Your healthcare provider will tell you which medicines to take or not take on the day of your MRI. He or she may give you medicine to help you feel calm and relaxed during the MRI.
- Tell your provider if you know or think you are pregnant.
- Tell your provider if you have any metal in your body, such as a pacemaker, implant, or aneurism clip. Tell him or her if you have a tattoo or wear a medicine patch.
- Remove any metal items, such as hair clips, jewelry, glasses, hearing aids, or dentures before you enter the MRI room.
What will happen during an MRI?
Your healthcare provider will ask you to lie on a table. Contrast liquid may be used to help a body part show up more clearly. The table will be moved into an open space in the middle of the machine. You will need to lie still during the MRI. It is normal to hear knocking, thumping, or clicking noises from the machine.
What are the risks of an MRI?
An MRI may cause a metal object in your body to move out of place and cause serious injury, or stop working properly. The contrast liquid may cause nausea, a headache, lightheadedness, or pain at the injection site. You could have an allergic reaction to the contrast liquid.
