A recent MRI installation caused some staff at an Illinois medical facility to lose the functionality of their Apple devices, including iPhones and Apple Watches, according to an article on the Becker's Health IT and CIO Report website.
The culprit was a recent MRI installation.
The Morris Hospital & Healthcare Centers staff investigated and determined the issue was linked to the release of helium during the installation.
When setting up an MRI, installers use evaporated helium to supercool the magnet inside the device. The helium should be directed out of the facility through a vent, but a leak allowed the chemical to enter other areas of the building.
