We thank Lee et al. for their comments.In our study, 52.1% of all 18 F-fluorodeoxygluocose positron emission tomography/computed tomography (FDG PET/CT) scans were considered clinically helpful, and 65.8% of abnormal scans contributed to the final diagnosis of fever of unknown origin (FUO). A meta-analysis shows that the 62.1% of the FDG-PET/CT findings contributed to obtaining a final diagnosis in cases of FUO. We agree that the role of PET/CT could have been overestimated in our study. The relatively high rate of contribution of PET/CT findings to the final diagnosis could have been due to the following reasons. First, as I described in the manuscript, patients in whom the cause of FUO was diagnosed during the first-line work-up were excluded. Although these patients are satisfactory the classic FUO criteria, they were excluded in our study.
