Core Points - The tragic incident involving a 61-year-old man named Keen occurred during an MRI scan, where he was fatally injured due to a heavy metal chain he was wearing being attracted to the MRI machine's magnetic field [1][2] - The MRI machine operates using a strong magnetic field, which can attract ferromagnetic objects, posing significant risks to patients and staff if safety protocols are not followed [11][12] - The incident highlights the importance of ensuring that patients do not carry any metal objects and the need for increased awareness regarding the materials in clothing, especially those containing silver fibers, which can cause burns during MRI scans [16][17] Summary by Sections Incident Overview - Keen was assisting his wife during her MRI scan when he was pulled towards the machine due to the magnetic attraction of his 9 kg metal chain, resulting in severe injuries and ultimately his death [1][2] MRI Technology - MRI is a non-invasive imaging technique that utilizes the magnetic properties of hydrogen atoms in water to create detailed images of internal body structures [4][6] - The machine generates a magnetic field typically ranging from 1.5 to 3 Tesla, which is significantly stronger than the Earth's magnetic field, leading to the potential for dangerous interactions with metallic objects [11] Safety Protocols - The incident underscores the critical need for strict adherence to safety protocols, including the prohibition of metal objects in the MRI room, to prevent accidents [12][14] - Additionally, the presence of silver fibers in clothing can lead to burns due to induced currents when exposed to the MRI's radiofrequency pulses, necessitating careful clothing checks before scans [16][17]
