Brief Summary

\[18F\]FTC-146 is a sigma-1 receptor detector and is an experimental radiotracer. Several studies have implicated involvement of sigma-1 receptors in generation and perpetuation of chronic pain conditions, while others are investigating anti sigma-1 receptor drugs for treatment of chronic pain. Using \[18F\]-FTC-146 and PET/MRI, we hope to learn what is the best approach to identify the source of pain generation and characterize the disease in pediatric patients with chronic pain.
