Purpose. This study evaluated the potential of68Ga-citrate positron emission tomography/computed tomography (PET/CT) for the detection of infectious foci in patients withStaphylococcus aureusbacteraemia by comparing it with 2-[18F]fluoro-2-deoxy-D-glucose (18F-FDG) PET/CT.Methods.Four patients admitted to hospital due toS. aureusbacteraemia underwent both18F-FDG and68Ga-citrate whole-body PET/CT scans to detect infectious foci.Results.The time from hospital admission and the initiation of antibiotic treatment to the first PET/CT was 4–10 days. The time interval between18F-FDG and68Ga-citrate PET/CT was 1–4 days. Three patients had vertebral osteomyelitis (spondylodiscitis) and one had osteomyelitis in the toe; these were detected by both18F-FDG (maximum standardised uptake value [SUVmax]6.0±1.0) and68Ga-citrate (SUVmax  6.8±3.5,P=0.61). Three patients had soft tissue infectious foci, with more intense18F-FDG uptake (SUVmax  6.5±2.5) than68Ga-citrate uptake (SUVmax  3.9±1.2,P=0.0033).Conclusions.Our small cohort of patients withS. aureusbacteraemia revealed that68Ga-citrate PET/CT is comparable to18F-FDG PET/CT for detection of osteomyelitis, whereas18F-FDG resulted in a higher signal for the detection of soft tissue infectious foci.
