MRIs Are Safe as long as There's No Metal in the Room
Briefly

A man died on Long Island after a metal chain around his neck was drawn into a magnetic resonance imaging (MRI) scanner. He was assisting his wife after her knee scan when the 20-pound chain was attracted to the MRI's strong magnet, causing him to be pulled into the machine. He suffered serious injuries and died the next day. MRI scanners use powerful electromagnets that attract ferromagnetic materials, making metallic objects near them highly dangerous projectiles, which underscores the importance of strict safety measures.

MRI scanners utilize strong magnetic fields generated by metal coils, which can attract ferromagnetic materials with force, posing severe safety risks.
