BACKGROUND Chronic Q fever usually presents as endocarditis or endovascular infection. We investigated whether 18F-FDG PET/CT and echocardiography were able to detect the localization of infection. Also, the utility of the modified Duke criteria was assessed. METHODS Fifty-two patients, who had an IgG titre of  ≥ 1024 against C. burnetii phase I ≥ 3 months after primary infection or a positiv...
