Why it was recalled

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.

Action the firm took

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).
