Since MRI (magnetic resonance imaging) scanners became available in the 1980's, they have rapidly become one of the most common clinical imaging tools. The MR environment produces unique safety and compatibility issues for materials used in implants and medical devices. The principal issues for MR safety and compatibility are magnetically induced displacement force and torque, radio frequency (RF) heating, and image artifact. This paper defines and discusses the potential hazards produced by implants and devices in the MR environment, with an emphasis on stainless steels. It also describes MR safety and compatibility test methods developed by ASTM and summarizes ongoing MR standards development work.
