FDG-PET for investigation of patients with fever of unknown origin

摘要

We read with interest the work of Kim et al. regarding the use of positron emission tomography (PET) with fluorodeoxyglucose (FDG) combined with computed tomography (CT) for investigation of patients with fever of unknown origin (FUO). We are concerned that the conclusions drawn from the case series do not match the data presented.It is erroneous to claim that PET/CT contributed to the diagnosis in 65.8%. Fewer than half of the cases in the series underwent the investigation. Additionally, the inherent nature of a retrospective series and the nonsys-tematic use of PET imaging in this study make it difficult to conclude other than that PET contributed to the diagnosis in about 23% of cases in a selected series. In the cases when PET was not undertaken, it is not known whether the investigation would have provided assistance.
