Monocentric Observational Study on the Diagnostic and Prognostic Role of 18F-PSMA PET (PET/CT and PET/MR) in Prostate Cancer

Study Overview
=================
Brief Summary
-----------------
The general objective of this retrospective and prospective study is to evaluate the diagnostic and prognostic role of a quantitative analysis of PET images with 18F-PSMA in all stages of the disease in patients with prostate cancer. To this end, both imaging parameters commonly used in clinical practice and the contribution of radiomic features will be investigated. The latter are quantitative features extracted from biomedical images, and are believed to be able to provide information, otherwise impossible to investigate, useful for the characterization of various pathologies. This methodology is very promising, but also recent and therefore little studied and standardized. Our objective is also to investigate how to optimize it from a purely methodological point of view.

Detailed Description
-----------------
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.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Diagnostic Test: PET 18F-PSMA|Subjects will be subjected to a PET examination according to international guidelines and where requested by the specialist. In particular, patients will be administered the radiopharmaceutical 18 F PSMA. Approximately two hours after administration, the patient is positioned on the PET/CT equipment table and image acquisition begins.|
