An MRI (Magnetic Resonance Imaging) scan uses radio waves, magnetism and a computer to produce images right onto the computer screen producing images of body parts. It is a radiology technique where a patient is positioned on a moving bed and goes inside the tube surrounded by a circular giant magnet.

The magnet creates a magnetic field that aligns the hydrogen proton atams which are exposed to a beam of radio waves. In result, parts of the body protons spin producing a faint signal that is detected by a part of the MRI scanner.

A computer then processes the information from the receiver and a detailed image is generated on the screen. An MRI scan is a popular tool used for different purposes including: detecting brain tumors, trauma to the brain and other abnormalities.

It provides information that is very valuable on the body organs and glands located within the abdomen, as well as joint structure, soft tissue, and bone information.
