Evaluation of diagnostic performance of 18F-FDG-PET compared to CT in detecting potential causes of fever of unknown origin in an academic centre.

Determining the cause of fever of unknown origin (FUO) often proves challenging to attending physicians and the role of conventional imaging in this setting has been uncertain. In this retrospective study, we examined the role of fluorine-18 fluorodesoxyglucose-positron emission tomography ( 18 FFDG-PET) compared to computed tomography (CT) in diagnosing the potential etiology of FUO. To accomplish this task, we identified patients with FUO who underwent 18
