Recall record

Recall number: Z-1353-2023
Classification: Class II
Status: Open, Classified
Initiated: 2023-03-01
Posted: 2023-04-07
Recalling firm: Shanghai United Imaging Healthcare Co., Ltd.
Product: Shanghai United Imaging Healthcare Co., Ltd. Positron Emission Tomography (PET) and Computed Tomography (CT), Model uMI 550 Part Number: 88000657 88000057
Product code: KPS System, Tomography, Computed, Emission
Reason for recall: Due to a software issue where the process of patient scanning, the scatter correction may occasionally fail with will potentially cause a failure of the PET image reconstruction and generation of PET images.
Root cause tag: software
FDA root cause: Software design
Action: On 03/01/2023, the firm sent an "Advisory Notification: Positron Emission Tomography and Computed Tomography System (PET/CT)" Letter via email to customers informing them that, the scatter correction may fail due to GPU (Graphic Processing Unit) memory access exception. The failure of the scatter correction could result in the failure of the PET image reconstruction. Customers are instructed to: 1. if the default PET image reconstruction fails with an error information of abnormal GPU status, but the reconstruction without either attenuation correction or scatter correction works successfully, the following actions are suggested to be applied: 1) Try using the diagnostic CT image series instead of ACCT image series for attenuation correction to repeat the PET reconstruction. It may resolve the error issue, but the quantification of PET image might be affected due to attenuation correction with using the limited field of view of diagnostic CT image. If the resulted PET image is insufficient for diagnosis, try second suggestion. 2) Try re-perform the PET acquisition, the reconstruction may succeed. 3) Contact the United Imaging service engineer to install the updated software to resolve the issue, and offline reconstruct the PET image. For questions, contact United Imaging service engineer or call the United Imaging Customer Contact Center (24- hour hotline) at 855-221-1552 (toll-free) or 832-699-2799 (direct).

About this record

Sourced from the FDA device recall database and the FDA enforcement reports, both ingested from openFDA. The recall record supplies the product, the reason and the product code; the enforcement report supplies the classification. The two datasets are exported by FDA on different days, and the date above is the older of the two, so nothing on this page is newer than it says.

MDM adds the root cause tag, derived from FDA’s own root cause text, and the cross-links to the product code, the clearances named on the record and MDM coverage. Where a recall has not been joined to an enforcement report, no classification is shown.
