Philips Spectral CT 750: Increased contrast volume risk with weight settings
Philips recalls Spectral CT 7500 X-ray systems that may increase contrast volume when set to pounds, potentially affecting patient imaging safety. Affected units have specific serial numbers and software versions.
Lower-risk recall
When setting patient weight unit preferences to pounds, SynchRight P3T (Personalized Patient Protocol) software will result in increased contrast volume, resulting in increased contrast volume recommended for the patient.

“Philips Spectral CT 750: Increased contrast volume risk with weight settings.” GovInfoNow, updated August 19, 2026. https://govinfonow.com/recall/62366-philips-spectral-ct-750-increased-contrast-volume-risk-with-weight. Based on FDA recall #Z-2318-2021 (https://api.fda.gov/device/enforcement.json?search=recall_number:%22Z-2318-2021%22&limit=1).
Why it’s dangerous
When the patient weight is set to pounds in the SynchRight P3T software, the system increases the recommended contrast volume for the patient. This could lead to higher contrast doses than intended, potentially affecting imaging safety. The hazard occurs only when weight units are manually set to pounds.
Who’s affected
Healthcare facilities using Philips Spectral CT 7500 X-ray systems with specific serial numbers and software version 5.0.0 are most at risk. Patients undergoing scans with these systems may be affected if weight settings are incorrectly configured.
How to tell if you have this one
Check for serial numbers starting with 10019 (01)00884838101111(21)10019 on the Spectral CT 7500 X-ray systems. The software version must be 5.0.0 with SynchRight Option installed.
