Small-caliber firearms can be hazardous in magnetic resonance (MR) imaging suites. Unloaded handguns were tested, and two of six discharged due to magnetic field interactions, highlighting safety risks.

Area of Science:

Medical Imaging Physics
Firearm Safety Engineering

Background:

Magnetic Resonance (MR) imaging utilizes powerful magnetic fields.
The interaction of metallic objects, including firearms, with MR imaging environments poses potential safety concerns.

Purpose of the Study:

To evaluate the safety of small-caliber firearms within a 1.5-Tesla (T) magnetic resonance imaging environment.
To determine the risk of accidental firearm discharge when exposed to MR imaging magnetic fields.

Main Methods:

Six unloaded, small-caliber handguns were tested in a 1.5-T MR imaging setting.
Firearms were withdrawn barrel-first to simulate handling within the magnetic field.
The interaction between the magnetic field and firearm components (hammer, trigger) was assessed.

Main Results:

Two of the six tested handguns discharged reproducibly during the assessment.
Accidental discharge occurred due to the interaction of the magnetic field with the firearm's mechanism.
The study identified specific risks associated with MR imaging and firearms.

Conclusions:

Firearms, even when unloaded, present a significant safety hazard in MR imaging suites.
Unloading firearms is insufficient to mitigate the risk of discharge in an MR environment.
Strict safety protocols, including avoiding firearm presence or manipulation, are essential in MR imaging suites.
