What is MRI and Why Do I need it?

Magnetic resonance imaging (MRI) is a safe and painless test that uses a magnetic field and radio waves to produce detailed pictures of the body’s organs and structures. Unlike CAT scans or X-rays, MRI doesn’t use radiation. An MRI scanner is a large doughnut-shaped magnet that often has a tunnel in the center. Patients are placed on a table that slides into the tunnel. Some hospitals and radiology centers use what are called “open” MRI machines. They have larger openings and are helpful for patients with claustrophobia (a fear of being in tight, enclosed spaces), but sometimes use a smaller magnet and might not have as high a quality image. During the MRI exam, radio waves manipulate the magnetic position of the body’s atoms, which are picked up by a powerful antenna and sent to a computer. The computer does millions of calculations to create clear, cross-sectional black-and-white images of the body. These images can be converted into three- dimensional (3-D) pictures of the scanned area that can help pinpoint problems in the body.

What to expect

  • Some exams require an injection of contrast, if contrast is needed an IV will be inserted.
  • It is important that you lay very still during the exam so the images will be clear.
  • You will hear loud tapping and knocking noises during the exam, earplugs will be provided.
  • You may feel warm during the exam which is normal. Notify the technologist if this becomes uncomfortable.
  • The technologist will communicate with you through out the exam to ensure you are comfortable.

MRI is used to:

Provide clear images of body parts that can’t be seen as well with an X-ray, CAT scan, or ultrasound. MRI is particularly helpful for diagnosing problems with the joints, cartilage, ligaments, and tendons. They can detect a variety of conditions, including problems of the brain, spinal cord, extremities, pelvis, wrists, hands, ankles, and feet and can identify infections and inflammatory conditions or to rule out problems such as tumors.

MRI Safety

The magnetic field is always “ON” and because of this even the smallest metal object can be pulled in. For your safety and the safety of others please remove all jewelry and/or metal before arriving for your MRI.
