Hazard Information

There is a potential for an ice blockage to form or currently 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. This pressure build-up could ultimately rupture the helium containment system, potentially resulting in a helium leak into the scanning room.

What You Should Do

Patients and healthcare providers should stop using this device immediately. Follow the recall instructions provided by the manufacturer. Contact Siemens Medical Solutions USA, Inc or your healthcare provider for instructions. Notification method: Letter

About This Product

The Biograph mMR is a PET-MRI system used by hospitals to perform combined metabolic and anatomic imaging. It plays a critical role in oncology, neurology, and cardiology diagnostics.

Why This Is Dangerous

Ice blockage in the magnet venting system may prevent helium gas from escaping during a quench. This can raise pressure and rupture the helium containment, potentially releasing helium into the scanning room.

Industry Context

This recall is not described as part of a broader industry pattern in the notice.

Real-World Impact

Hospitals must halt use of affected units. Depending on remediation timing, patient imaging schedules could be disrupted and safety precautions must be strictly followed.

Practical Guidance

  1. Verify device model number is 10433372.
  2. Check the UDI list for matching identifiers.
  3. Confirm the unit count in your facility equals 23 globally affected units.

Where to find product info
