Siemens Biograph mCT-S PET/CT Scanners Recalled for Calibration Error

Siemens Medical Solutions is recalling 100 Biograph mCT-S PET/CT scanners because using non-Siemens phantoms for calibration may result in unexpected SUV values.

What this means for you

Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.

Our severity reasoning: The recall is classified as FDA Class II, and the hazard involves potential measurement inaccuracy (unexpected SUV values) rather than a direct physical injury or high-risk pathogen, fitting the criteria for moderate severity.

Plain-English summary

Siemens Medical Solutions USA Inc. is recalling 100 units of the Biograph mCT-S(40) 4R, a combined X-Ray Computed Tomography (CT) and Positron Emission Tomography (PET) scanner. The recall is due to a potential for unexpected Standardized Uptake Value (SUV) readings if a non-Siemens phantom is used for the device's calibration.

The affected units are distributed worldwide and across the United States. The recall covers specific serial numbers listed in the agency's official documentation. The hazard is limited to the accuracy of the calibration process when third-party equipment is utilized.

Healthcare facilities and users of these devices should verify their calibration procedures to ensure that only approved Siemens phantoms are used to maintain accurate SUV values.
