Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI) is a dynamic way for doctors to diagnose certain diseases. MRI doesn't rely on x-rays. Instead, it uses a magnetic field and radio waves to create a very clear picture of internal body structures.

MRI has become a preferred method for diagnosing potential problems in many different parts of the body. While X-rays are best for showing bones, MRI creates pictures that can show differences between healthy and unhealthy tissue. Doctors use MRI to examine soft tissue - like organs, muscle, cartilage, ligaments and tendons in many parts of the body.

The examination itself is performed in a room that houses the MRI equipment. You'll be asked to lie down on a comfortably padded table that gently glides you into the magnet. While the scanner is operating, you'll hear some humming and occasional thumping sounds. These are normal and shouldn't worry you. In some cases, your doctor may have requested that you receive an injection of a contrast agent to give a clearer picture of the area being examined.

The most important thing for you to do is relax and lie still. Most exams take between 30-45 minutes, although some may take as long as 60 minutes.
