Siemens SOMATOM Scope CT Scanner Recalled for Incorrect Radiation Dose Calculations
Siemens Medical Solutions is recalling SOMATOM Scope CT scanners because the CARE Dose4D algorithm may incorrectly calculate tube current for head scans, potentially leading to unnecessary radiation exposure.
The agency’s classification
FDA (Devices): Class II
Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.
This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work
What this means for you
Our assessment, not the agency’s: severity 3/5 (High).
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: The recall involves a risk-of-harm product (unnecessary radiation exposure) where injury has not yet been reported, fitting the High severity criteria.
Plain-English summary
Siemens Medical Solutions USA, Inc. is recalling 1,301 units of the SOMATOM Scope CT scanner. The device is intended to produce cross-section images of the body by computer reconstruction of x-ray transmission data. The recall was initiated to inform customers of possible incorrect tube current calculations by the CARE Dose4D algorithm for head scans based on posterior-anterior or anterior-posterior topograms.
Depending on the geometrical shape of the skull bone, the calculated dose distribution may be inappropriate in rare cases. This error could lead to unnecessary radiation exposure for patients. The affected units were distributed nationally in the United States.
Customers should contact Siemens Medical Solutions USA, Inc. for further instructions regarding the recall and potential corrective actions.
