Magnetic resonance imaging (MRI) is a test that uses
a magnetic field and pulses of radio wave energy to make pictures of organs and
structures that are inside the body. During the MRI test (also called an MRI
scan), you usually lie on your back on a table that is part of the MRI scanner.
Your head, chest, and arms may be held with straps to help you stay still. The
table will then slide into the round opening of the magnet.
the scanner you will hear a fan and feel air moving. You may also hear tapping
or snapping noises as the MRI scans are done. It is very important to stay
completely still while the scan is being done.
People who get
nervous in small places (are claustrophobic) may need medicine to help them
relax while having an MRI scan.
