MRI Hazards The American Journal of Roentgenology has reported on lethal incidents occurring in magnetic resonance imaging (MRI) suites in US hospitals. These incidents are not side-effects of the procedure per se, but flying objects strongly attracted to the magnetic force of the MRI.
Objects flying through the air have included ferromagnetic nitrous oxide or oxygen tanks, a defibrillator, a wheelchair, a respirator, ankle weights, a tool box, a vacuum cleaner, and mop buckets. The objects are attracted to the magnet with such force they become projectiles.
The authors of the study, from the University of Texas, believe it is likely that such incidents are under-reported and that they may be increasing.
Human error and failure to follow safety policies were cited as common causes of the accidents. The authors propose controlled entry to imaging facilities.

Very good idea. I heard about a cop who wandered into a MRI room and had his gun ripped out of his holster.
