Moderate to intense <sup>18</sup>F-FDG valvular uptake was also associated with worse outcome (HR: 2.3; 95% CI: 1.3 to 4.5; p = 0.03) and to new embolic events in PVE (HR: 7.5; 95% CI: 1.24 to 45.2; p = 0.03) and in NVE (HR: 8.8; 95% CI: 1.1 to 69.5; p = 0.02).
In patients with possible or rejected NVE according to the modified-Duke criteria, F-FDG-PET/CT could be used in case of sustained suspicion of NVE owing to its high specificity in case of abnormal FDG uptake at the valve region.
