↵* Days between index vascular operation and PET/CT scan.
↵† 1 = background activity; 2 = mildly increased but diffuse 18F-FDG uptake along graft; 3 = focal but only mild uptake or strong and diffuse uptake along graft; 4 = focal and intense uptake (with or without diffuse uptake along graft); 5 = focal and intense uptake plus fluid collections or abscess formation (16).
