A 61-year-old man named Keith McAllister died on Long Island, New York, after being pulled into an active MRI machine by a heavy metal chain necklace weighing approximately 9 kilograms (20 pounds) that he was wearing. The incident occurred at a medical facility in Westbury when McAllister entered the MRI room during a scan, allegedly despite warnings from the technician. The powerful magnetic field of the MRI machine attracted the metal chain, causing the fatal accident. Authorities and family members have noted that the technician may have failed to adequately warn McAllister about the dangers of entering the MRI room with metal objects. The man was reportedly wearing the chain while his wife was undergoing a scan. The case highlights the critical safety risks associated with metal objects near MRI machines.
