FDA has published a guidance, *Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment*, with its recommendations on testing to assess the safety and compatibility of medical devices in the magnetic resonance environment and the recommended format for magnetic resonance imaging safety information in medical device labeling. The [document](https://www.fda.gov/regulatory-information/search-fda-guidance-documents/testing-and-labeling-medical-devices-safety-magnetic-resonance-mr-environment?ref=fdaweb.com) supersedes a 12/11/2014 guidance.

Contents in the guidance are Introduction, Scope, Terminology, Relevant Consensus Standards and Guidance Documents, Addressing Hazards for Medical Devices in the MR Environment, Extent of Image Artifact, Reporting Results, MRI Safety Labeling, and two appendices.
