Patient Safety Topics
Magnetic Resonance

​​​​​​​​​​​A magnetic resonance imaging (MRI) scanner has strong forces that can move an internal ferromagnetic object (made of or having parts made of substances such as iron, nickel, and cobalt), which can be magnetized by exposure to a magnetic field. Further, the scanner can erase the memory or impair the function of a medical device and turn a ferromagnetic object into a projectile that can injure or kill. Because of this magnetic field and the associated radiofrequency energy, providing MRI screening for patients and staff is critical to their individual safety. Screening ensures that no ferromagnetic objects or objects (in or on anyone) that conduct electricity enter the MR scanning area.
