F-FDG PET/CT demonstrated high sensitivity for the diagnosis of patients with FUO. F-FDG PET/CT is an accurate technique in this setting, but the possibility of false-positive results should be kept in mind. This meta-analysis demonstrated the value of F-FDG PET/CT in the diagnosis of patients with FUO.

The results of our study indicate that both early and delayed phase (99m)Tc-sestamibi SPECT/CT should be performed in the preoperative evaluation of hemodialysis patients with sHPT due to chronic kidney disease. Performance of both early and delayed phase (99m)Tc-sestamibi SPECT/CT did not increase the radiation dose compared with the use of only the early or the delayed phase.

In patients with CHI, F-DOPA PET or PET/CT demonstrated high sensitivity and specificity. F-DOPA PET and PET/CT are accurate methods for the diagnosis of CHI. Nevertheless, possible sources of false-positive and false-negative results should be kept in mind.
