What this means for you

Highest-severity recall. Risk of serious injury or death is documented or strongly suspected. Stop using the product now and follow the agency's instructions.

Our severity reasoning: Scored 5 because the FDA classified this recall as Class I, which the rubric assigns the Critical tier.

Plain-English summary

The BIOGRAPH One (DE) system, model number 11689172, is being recalled because an ice blockage may form, or may already exist, within the magnet venting system.

In the event of a quench, helium gas may be unable to escape through the designed venting paths, leading to a pressure build-up within the helium containment system. That pressure build-up could ultimately rupture the helium containment system, potentially resulting in a helium leak into the scanning room.

The recall covers one unit, serial number 238008, from a worldwide distribution that includes the United States. The FDA has classified the recall as Class I.

The operating site should follow the manufacturer's instructions for inspection and correction of the venting system before further use.
