Potential usefulness of Ga-citrate PET/CT in detecting infected lower limb prostheses.

Background: Prosthetic joint infections may lead to failures of total joint arthroplasty. Radionuclide imaging can play a diagnostic role in identifying such infections, which require two-stage exchange arthroplasty (instead of simple revision surgery performed in non-infected cases). Although F-FDG PET/CT has emerged as a novel diagnostic tool in this setting, the clinical usefulness of Ga-citrate PET/CT has not been previously investigated.

C-reactive protein levels can predict positive F-FDG PET/CT findings that lead to management changes in patients with bacteremia.

Background/purpose: Bacteremia portends high rates of morbidity and mortality. Although F-fluorodeoxyglucose positron emission tomography and computed tomography (F-FDG PET/CT) imaging has clinical value in assessing fever of unknown origin, its usefulness in bacteremia has not been entirely elucidated. We therefore designed the current single-center retrospective study to investigate 1) the clinical value of F-FDG PET/CT imaging in assessing bacteremia and 2) the association between laboratory data and imaging findings.

Clinical utility of FDG PET/CT in acute complicated pyelonephritis-results from an observational study.

Background: Acute complicated pyelonephritis (ACP) is an upper urinary tract infection associated with coexisting urinary tract abnormalities or medical conditions that could predispose to serious outcomes or treatment failures. Although CT and magnetic resonance imaging (MRI) are frequently used in patients with ACP, the clinical value of F-fluorodeoxyglucose positron emission tomography and computed tomography (FDG PET/CT) has not been systematically investigated. This single-center retrospective study was designed to evaluate the potential usefulness of FDG PET/CT in patients with ACP.
