Action Taken
On 08/02/2021, the Firm emailed to its customer an "Advisory Notification" informing them of a potential safety-relevant issue in which the EXAM acquisition workflow could occasionally freeze after canceling the PET scan. The issue and the sequence of events leading to this occurrence are as follow: During a myocardial perfusion scan procedure, the follow steps could lead to the EXAM acquisition workflow to occasionally freeze- 1. Selecting the myocardial perfusion scan procedure and entering EXAM. 2. Finishing the CT scout and helical/cine scan. 3. Starting the PET scan. 4. Canceling the current PET scan -- in this case the EXAM acquisition workflow may shut down, resulting in an error message stating: "EXAM (Study ID: XXXXXXX) has some errors, trying to restart. Please wait and try again. 5. Reentering the EXAM acquisition workflow without restarting the system, and then attempting to continue the scan. If the above occurs, this may require rescanning of the patient, resulting in additional CT dose exposure. Customer are instructed to: 1. When the EXAM acquisition workflow is interrupted after cancellation of the scan, follow the steps to resume the procedure: a) Wait until CT reconstruction finishes. b) Perform a system restart. c) After restart, select the suspended procedure on the patient administration (PA) interface and enter EXAM. System will load and recover the status of this procedure. d) Duplicate or copy and paste the unfinished PET scan, and then continue. 2. Please notify all internal users of the PET/CT system, using this letter. 3. Complete and sign the Receipt of Advisory Notification Form and return it to the Recalling Firm via fax, email or mail. The Recalling Firm is working on releasing a software update to resolve this issue. Planned release of software update is Q4 of 2021.
