Evaluation of the Diagnostic and Prognostic Role of PET (PET/CT and PET/MRI) in Neuroendocrin Tumors.

The aim of this retrospective study is to evaluate the diagnostic and prognostic value of PET/MRI and PET/CT with the use of different radiopharmaceuticals (68Ga-DOTATOC -edotreotide, and 18F-FDG - fluorodeoxyglucose) for the study of patients suffering from neuroendocrine tumors. To this end, both traditional imaging parameters 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.
