What is the term for the potential for a metallic object to move violently toward the MRI magnet?

The term for the potential for a metallic object to move violently toward the MRI magnet is the "missile effect." This phenomenon occurs due to the strong magnetic field generated by the MRI scanner, which exerts a powerful force on ferromagnetic objects, causing them to be attracted at high speeds. This effect poses significant safety risks in the MRI environment, as any metallic item—whether a tool, clip, or even a patient's implanted device—can become a projectile if it is not properly managed.

Understanding the missile effect is crucial for MRI safety protocols. Professionals in the field must be aware of the types of materials that are safe to enter the MRI room, and ensure that all metallic objects are removed or adequately secured to prevent accidents. This awareness plays a vital role in maintaining a safe scanning environment for both patients and staff.
