In an MRI, if a patient is pinned by a large metallic object, which course of action is appropriate?

• A. Stop the scan immediately to release the magnet
• B. Summon enough people to pull the object away
• C. Interrupt electrical power for 60 seconds to release the magnetic force
• D. None of the above

Answer: (D)

In MRI situations, the main hazard is the strong static magnetic field that can grab and pin ferromagnetic objects, turning them into dangerous projectiles. Because of this, you cannot rely on simple fixes like stopping the scan, pulling the object out, or interrupting power to release the patient—the magnetic force remains regardless of these actions. The appropriate course is to follow established MRI safety protocols: halt the procedure using the emergency stop and summon trained MRI safety personnel to manage the situation, using MRI‑safe equipment to assist and remove the patient if possible. A magnet quench is a last‑resort, highly specialized action with its own serious risks, not a routine fix. Since none of the listed options alone provides a safe, effective resolution, none of the above is the correct immediate approach.
