MRI scan facts

  • MRI scanning uses magnetism, radio waves, and a computer to produce images of body structures.
  • MRI scanning is painless and does not involve x-ray radiation.
  • Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.
  • Claustrophobic sensation can occur with MRI scanning.
