Magnetic Resonance Imaging Safety

Although magnetic resonance (MR) imaging does not use ionizing radiation, it has its own safety issues. MR safety concerns are associated with the static magnetic field, radiofrequency burns, scanner acoustic noise, and the use of gadolinium-based contrast agents. MR technologists have a responsibility to thoroughly screen patients and personnel before they enter the magnetic field and to research patient implants and devices to determine under what conditions the patient can be scanned safely. During long scans, MR technologists also must monitor patients to avoid adverse events. This article is useful for non-MR technologists who might work in the MR environment or who are considering cross-training in this important discipline.
