Keith McAllister, 61, died after he entered an MRI room at Nassau Open MRI in Westbury last week while a scan was in progress.

The man was wearing a large metal necklace when he entered a room where the machine, which uses a powerful magnetic field to create images, was operating.

A man who was sucked into an MRI machine at a Long Island medical office because he was wearing a metal chain as a scan was in progress has died from his injuries, according to police.
