MRI machines are known for their powerful magnets, capable of providing detailed images of the human body. However, their immense magnetic pull also poses significant risks, especially when metal objects are present. A recent incident in the United States illustrates the grave consequences of ignoring MRI safety protocols.
The Incident
In June 2023, a 57-year-old woman entered an MRI (magnetic resonance imaging) room carrying a concealed handgun. The powerful magnetic field of the MRI machine pulled the iron gun from her possession, causing it to discharge. The bullet struck her right buttock, resulting in small entry and exit wounds. Fortunately, her injuries were superficial, and she made a full recovery after on-site medical evaluation.
A Failure in Pre-Scan Screening
MRI procedures require rigorous pre-scan screening to ensure no metal objects enter the room. Despite undergoing this process, the woman failed to disclose her concealed firearm. This oversight highlights the critical importance of patient honesty and adherence to safety protocols.

The Science Behind MRI Hazards
MRI machines create magnetic fields thousands of times stronger than a refrigerator magnet. These fields align hydrogen nuclei in the body to generate detailed medical images. However, ferromagnetic materials like iron are intensely attracted to the magnets, turning objects such as firearms into dangerous projectiles.
Similar Accidents Highlight the Risks
This incident is part of a troubling trend of accidents involving metal objects in MRI rooms. Earlier this year, a Brazilian man died after his concealed gun discharged near an MRI scanner, and in 2018, a Long Island man’s firearm injured him when it discharged during a scan. But it isn’t all firearm related, as a gurney crushing a nurse in an MRI room due to the magnetic pull.
Lessons on Patient and Staff Vigilance
This case underscores the need for vigilance among both patients and medical staff. Patients must adhere to the “no metal” rule, and staff must ensure thorough screenings to identify concealed objects. MRI safety protocols are non-negotiable to prevent such incidents.
Why Honesty Matters in MRI Screenings
The safety of MRI scans depends on patients being forthright about any metal objects. From pacemakers to firearms, even small oversights can have dangerous consequences. As experts note, “The magnets don’t discriminate; any metal is a risk.”
A Reminder to Prioritize MRI Safety
This incident is a stark reminder of the power and potential danger of MRI machines. While they are critical diagnostic tools, their strong magnetic fields require absolute compliance with safety measures. Proper education and rigorous pre-scan screenings can prevent such accidents and ensure these life-saving devices remain safe for all.
