Recall record

Recall number: Z-0307-2019
Classification: Class II
Status: Terminated
Initiated: 2017-06-07
Posted: 2018-10-31
Terminated: 2019-07-03
Recalling firm: Philips North America LLC
Product: Brilliance Big Bore Radiology CT (Model No. 728244) software version 4.2.0 Product Usage: Computed Tomography X-ray systems intended to produce cross-sectional Images of the body by computer reconstruction of X-ray transmission data taken at different angles and planes. These devices may include signal analysts and display equipment, patient and equipment supports, components, and accessories.
Product code: JAK System, X-Ray, Tomography, Computed
Reason for recall: It was reported that scanners running certain software versions provide confusing information in the "Impressions" section of the Calcium Score report. The generated report provides multiple analyses of the amount of plaque detected, as if they all apply to the patient at the same time. This misleading guidance can be potentially misleading to the user, and may lead to mistreatment of the patient.
Root cause tag: software
FDA root cause: Software design
Action: The recalling firm sent Customer Information letters dated June 7, 2017, to affected customers. The letter notified customers of the product issue. Customers were instructed to determine whether they had a potentially affected system by checking the software version of their device. Customers were reminded that the "Impressions" section of the report is not intended for diagnostic use. Users should instead focus on the total calcium score shown in the "Findings" section, the coronary artery score(s) and/or the "Age and Gender" graph as identified in the Instructions for Use (IFU). The firm sent a follow-up dated July 3, 2018, to inform customers that software updates had been released which resolved the issue. If you need any further information or support concerning this issue, please contact your local Philips representative: For North America and Canada, contact the Customer Care Solutions Center (1 -800-722-9377 and follow the prompts).

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.
