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?

What will happen during an MRI?

Your healthcare provider will ask you to lie on a table. 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. This may cause serious injury, or stop the object from working properly.
