The safety of small-caliber firearms in a 1.5-T magnetic resonance (MR) imaging environment was assessed with six handguns, which were unloaded before testing. Each firearm was withdrawn barrel-first to assess the interaction of the magnetic field with the hammer and/or trigger. Two of the six weapons discharged reproducibly. A firearm in an MR imaging suite should be unloaded before removal or any other manipulation is attempted.
