Observational study in PET-MRI using the 5-HT1A agonist PET radiotracer \[18F\]F13640.
Study Type
OBSERVATIONAL
Enrollment
12
Patients will performed PET-MRI scans. A first 30 minutes acquisition will be performed at time=60min after injection. A second 75 minutes acquisition will be performed at time=150min. Each scans will contain functional dynamic \[18F\]F13640 PET acquisition, anatomical and functional MRI images acquisition and pain evaluation using a score visual analogic scale.
