In this study, all PET images with 18F-PSMA will be considered, but also the CT or MR images associated with them to allow better anatomical localization.
This study will allow us to investigate the diagnostic and prognostic role of l8F-PSMA PET, also evaluating its predictive value in terms of disease course, development of metastases and mortality. The retrospective part of this protocol is necessary for the acquisition of a sufficiently large amount of data to guarantee adequate statistical power for the study.
