MR Screening Compliance Tool

We've put together a summary of what you'll need to know!


All Non-MR Personnel needing to enter Zone III must first pass an MR safety screening process. Before Non-MR Personnel enter Zone III, final authorization must originate from Level 2 MR Personnel. 

Nonemergent patients should be MR safety screened at least twice prior to being granted access to the MR environment. At least 1 of these screens should be performed by Level 2 MR Personnel verbally and/or interactively. For example, the patient (or their health care proxy) may complete a screening form and subsequently have the responses and contents of that form reviewed together with a Level 2 MR Technologist.  

Emergent patients and their accompanying Non-MR Personnel may be screened only once, provided that the screening individual has Level 2 MR Personnel status. Any exceptions to this (such as but not limited to cases where a screening induced delay may result in imminent patient paralysis, blindness, and/or death) must be with the mutual agreement of the ordering physician and covering Level 2 MR Physician, who specifically acknowledge the potential risks of a decision NOT to screen prior to granting that patient MR access.  

The screening process and forms for patients, Non-MR Personnel, and MR Personnel should be essentially identical. Specifically, one should assume that screened Non-MR Personnel, health care practitioners, or MR Personnel might enter the bore of the MR system and be exposed to the static and/or time-varying magnetic fields at any time.  

Examples of this include if a pediatric patient cries for his mother, who then leans into the bore of the scanner, or if an anesthesiologist leans into the bore to manually ventilate a patient in the event of a problem.  

Careful screening for ferromagnetic materials by direct inspection and use of a ferromagnetic detector is recommended prior to entering Zone IV. MR Conditional devices may be ferrous, which can lead to activation of ferromagnetic detectors prior to entry into Zone IV. The manufacturers of ferromagnetic detectors today do not claim utility or sensitivity for screening of implants or foreign bodies within patients, although if sufficiently large and/or superficial, implant detection may be possible.  

Staff/Personnel Screening  

All MR Personnel are to undergo an MR screening process as part of their employment agreement to ensure their safety in the MR environment. For their own protection and for the protection of the Non-MR Personnel under their supervision, all MR Personnel must immediately report to the MRMD any trauma, procedure, or surgery they experience or undergo where a ferromagnetic object or device may have become introduced within or on them. This will permit appropriate screening of the employee to determine the safety of permitting that employee into Zones III and/or IV.
