MRI has the risk of dislodging any type of metal that may be in the person, such as prosthesis and/or dental fillings made of metal. It's also possible that any accumulation of metal in tissue may cause damage in surrounding tissue. Those are relatively low risks, but they are risks, and the justification for an MRI is that the diagnostic information gained has a medical benefit that exceeds the medical risk of the procedure.
So, people without metal in them cannot undertake an MRI procedure. But, knowing this, what are the odds that psychopaths, sociopaths, impulsive murderers, paranoid-schizophrenics, might instill a metal in their broken bones (self or other inflicted broken bones at that) in purpose, just to avoid brain scans?
That's not a medical value, in the sense that if there is no indication of a problem, then the procedure is unwarranted medically. And certainly not on a recurring basis, which would be outcome for multiple gun purchases over time.
Medical or not, it just a matter of policy for MRI's to be used for other than medical purposes.
