Prostate cancer (PCa) is the most common solid cancer affecting men worldwide. Serum prostate-specific antigen (PSA) is at present the most commonly used biomarker for PCa screening, as well as a reliable marker of disease recurrence after initial treatment. Bone metastases (BM) are present in advanced stages of the disease. ⋯ So, 18 F-PSMA-1007 PET/CT imaging seems to be very promising in staging and restaging patients with PCa, especially when biochemical relapse is under consideration. Although it seems to perform better than other imaging modalities like bone scan, 18 F-FDG PET/CT or 18 F-choline PET/CT, its high cost and low availability must be considered. Further large studies need to be conducted in order to evaluate the accuracy and the predictive values of this method, emphasizing on bone metastases.

To evaluate the role of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in identifying the cause of fever of unknown origin (FUO) in patients on renal replacement therapy (RRT) for end-stage renal disease (ESRD). ⋯ About half of the 18F-FDG-PET/CT scans (22/46) identified the cause of FUO in patients on RRT for ESRD. The clinical utility of 18F-FDG PET/CT in this group of patients is comparable to its average performance in the unselected patients' population evaluated for FUO. A higher CRP level was predictive of a positive 18F-FDG PET/CT outcome.
