Cryogen transfills should only be performed with appropriate precautions in place to prevent against pressure entrapment and asphyxiation. I n my 30 years of clinical experience with MRI at one institution, I have observed several unexpected magnet quenches as well as a few planned quenches in conjunction with decommissioning older magnets. 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. Store cryogen containers in cool, dry, well-ventilated areas, away from incompatible materials and ignition sources.
