Siemens Biograph PET/CT Scanners Recalled for Calibration Error Risk
Siemens is recalling two Biograph PET/CT scanners due to a potential for unexpected SUV values if a non-Siemens phantom is used for calibration.
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, but the source text does not report any hospitalizations, injuries, or illnesses. The hazard is a potential for incorrect calibration values, which fits the criteria for a moderate severity recall involving a risk of harm where injury has not yet been reported or a precautionary measure.
Plain-English summary

The affected units are identified by serial numbers 1007 and 1008, with material number 10246389. These systems were distributed worldwide and across the United States.
The recall was initiated because Siemens Medical Solutions, Molecular Imaging became aware of a potential for unexpected Standardized Uptake Value (SUV) values if a non-Siemens phantom is used for calibration. The source text does not report any specific injuries, illnesses, or deaths associated with this issue.
