Summary
Brief summary (as posted)
18F-FDOPA PET-CT is currently the gold standard in the evaluation of Pheochromocytomas and Paragangliomas (PHEO - PGL) since these tumors can also decarboxylate amino acids such as dihydroxyphenylalanine (DOPA). This property is common to tumors of the APUD system (Amine Precursor Uptake and Decarboxylation). In recent years, PET (Positron Emission Tomography) imaging using peptide receptors has gained an increasing role in the management of NETs. The use of somatostatin agonists, radiolabeled with gallium-68 (68Ga) enables targeting of Somatostatin receptors (SSTRs) with a PET resolution. This has improved diagnosis of SSTRs-expressing tumors, including PGLs. In the present study, the investigators have chosen DOTATATE (Nal3-octreotate) rather than other agonists (DOTATOC and DOTANOC), because of its higher affinity for SST2 which is the most overexpressed subtype in PHEO/PGL. However, performances of 18F-FDOPA PET-CT and 68Ga-DOTATATE PET-CT have never been compared in this clinical setting.

Primary outcomes (1)
- measure
- interest of the the contribution of 68Ga-DOTATATE PET-CT in the staging of PHEO/PGL
- timeFrame
- 7 months
- description
- The primary outcome measure is to determine the contribution of 68Ga-DOTATATE PET-CT in the staging of PHEO/PGL. We will document the number of additional foci detected by 68Ga-DOTATATE PET-CT compared to 18F-FDOPA PET-CT.
Secondary outcomes (1)

- assesment of 68Ga-DOTATATE PET-CT to anatomical imaging
- timeFrame
- 7 months
- description
- The secondary objective is to compare , to assess the factors influencing its sensitivity concerning the tumor location
