FIGURE 1.  ¹⁸F-FDG PET (from left to right: coronal, sagittal, and transversal slices) of 65-y-old patient with long-standing FUO 6 y after revision of aortic aneurism, which was replaced by vascular graft. PET scan demonstrates elevated uptake in graft extending to adjacent tissue. Infection of graft was subsequently proven during diagnostic work-up.
