The unique nature of this technology presents special imaging, patient care, and safety requirements. Since magnetic resonance does not involve the use of ionizing radiation, radiation protection is unnecessary. However, patients must remove any metal objects that could be drawn to the magnet. Patients with pacemakers or other metallic implants can not undergo magnetic resonance scans because of the potential for damage to such devices.
Claustrophobia is sometimes a problem for certain patients.
Some magnetic resonance procedures require the use of contrast agents. The image obtained from magnetic resonance scan generally appears on a computer monitor or as a photograph or computer printout.
