MR Safety

MR Safety continues to evolve and in response, the ACR's Committee on MR safety created the ACR Manual on MR Safety with updates and critical new information which replaces all earlier versions of the ACR Guidance Document on MR Safe Practices. The ACR Manual on MR Safety addresses numerous MR safety-related topics such as:

  • MR Personnel
  • Screening
  • Gowning
  • Full-stop/Final Check
  • Special Patient Population Considerations
  • Implants, Devices and Objects
  • MR Environments to include 7T and intraoperative MR environments
  • Static Magnetic Fields
  • Time-Varying Gradient and RF Magnetic Field-Related Issues
