放射線科以外の医師へのMRI安全性周知：特に磁性体の吸着について

抄録

　Although magnetic resonance imaging (MRI) studies offer a significant advantage over computed tomography (CT) regarding radiation exposure, they are not without risks. Our institution has experienced MRI-related projectile incidents, such as the attraction of drug trays, syringe pumps, penlights, and power ankle bracelets, all of which involve physicians besides radiologists. Following an accident in 2024, in which a stretcher brought in by an intern caused severe damage to the MRI machine, we initiated an annual MRI safety training for all interns and hospital staff. Currently, the MRI safety training is not mandatory in Japan, resulting in inconsistent safety protocols across hospitals. The enactment of regulations similar to those governing radioactive isotopes could lead to widespread implementation of MRI safety training across hospitals nationwide, thereby enhancing the quality of medical care.
