Feasibility Study of 68Ga-PSMA PET-CT and 18F-FDOPA PET-CT in Glioblastoma's Patients

Overview

This study is a non-randomized, prospective, multicentric feasibility study assessing 68Ga-PSMA PET-CT and 18F-FDOPA PET-CT to differentiate early recurrence from post-radiation modifications in patients treated with radiotherapy for glioblastoma. Patients with a MRI performed since the end of the radiotherapy until 12 months of follow up after the end of radiotherapy, will be referred for both 68Ga-PSMA and 18F-FDOPA PET-CT, whatever the conclusion of the MRI (post radiation modifications, relapse or doubtful MRI). The rationale of doing 68Ga-PSMA and 18F-FDOPA brain PET-CT in each case will be discussed in detail with the referring physician and an informed consent will be taken from each patient for the study. The two imaging studies will be done at least with a gap of 6 hours, using the same PET-CT scanner.
