[International guidelines on the diagnostic applications of magnetic resonance. International Non-Ionizing Radiation Committee of the International Radiation Protection Association].

Magnetic resonance imaging has become an established diagnostic modality. The clinical usefulness of in vivo magnetic resonance spectroscopy was demonstrated in several instances and is being explored further. These techniques involve exposure of the patient to static and time-varying magnetic fields and radiofrequency electromagnetic fields. In particular exposure situations, these fields may pose a health hazard. The purpose of this paper is to provide information on the guidelines issued by the International Non-Ionizing Radiation Committee of the International Radiation Protection Association on levels of exposure and health effects from magnetic and radiofrequency electromagnetic fields associated with magnetic resonance diagnostic devices, and on precautions to be taken to minimize health hazards to patients undergoing magnetic resonance examinations.
