PET/MRI in the Diagnosis of Chronic Pain

Several studies have implicated involvement of sigma-1 receptors (SR1s) in the generation of chronic pain, while others are investigating anti SR1 drugs for treatment of chronic pain. Using [18F]-FTC-146 and positron emission tomography/magnetic resonance imaging (PET/MRI), the investigators hope to identify the source of pain generation in patients with chronic pain. The purpose of this study is to compare the uptake of [18F]FTC-146 in healthy volunteers to that of individuals suffering from chronic pain.

Stanford is currently accepting patients for this trial.
