What is MRI?
Magnetic resonance imaging (MRI) is a method used by physicians to look inside the body. Incorporating an advanced technology, MRI produces images of the anatomy without the use of radiation, as in X-ray and CT scans. MRI images are formed by computer processing signals emitted by body tissue. These signals are generated using a safe magnetic field in combination with radio waves of a specific frequency, similar to what is used in home and car radios.
