Magnetic Resonance Imaging (MRI) capture images of the body’s anatomy using magnetic fields and radio waves, not radiation. These machines can capture highly detailed images that are used to diagnose various conditions.

MRIs are often used in the diagnosis of:

  • Brain Disorders
  • Traumatic Injuries
  • Eye Abnormalities
  • Spine Diseases
  • Liver and Abdominal Diseases
  • Knee Injuries
  • Tumors
  • Musculoskeletal Disorders
  • Shoulder injuries
  • Facial and Neck Abnormalities
  • Infection
  • Heart conditions
  • Blood Flow and Vessel Disorders

What happens during an MRI?

MRIs are large, tube-shaped devices. You will lie on a table that slides into the tube and takes images of your body. In some instances, your entire body will need to be in the tube for the test to be effective. This can be difficult for patients with claustrophobia (fear if small spaces). If you have trouble staying still in enclosed spaces, the doctor can provide you with a sedative beforehand. There is also an intercom in the MRI that will allow you to communicate with the technologist during the entire procedure.

MRIs are painless and noninvasive. Tests can last anywhere between 10 minutes to over an hour. Be prepared to lie still for some time.

Your doctor may ask that you do not eat or drink anything for up to 12 hours before the procedure. This includes water and chewing gum. Because MRIs use magnetic fields, you will also need to remove any metal from your body and inform your physician and technologist if you have a pacemaker or other metal implant.
