2. What is MRI?

doctors to find certain diseases
or abnormal conditions.
3. MRI
o MRI does not rely on the type of radiation used for an x-
ray or computer tomography (CT) scan.
o The MRI examination requires specialized equipment
that uses a powerful, constant magnetic field, rapidly
changing local magnetic fields, radiofrequency
energy, and dedicated equipment including a powerful
computer to create very clear pictures of internal body
structures.
4. Is MRI Safe?
o MRI has been shown to be extremely safe as long as
proper safety precautions are taken.
o In general, the MRI procedure produces no pain and
causes no known short-term or long-term tissue damage
of any kind.

examination in process.
