Seeing pain: new scan aims to spotlight troublemaker nerves

This trial tests whether an investigational imaging agent called [18F]FTC-146, used with a PET/MRI scan, can identify the specific nerves responsible for chronic pain. Participants with chronic pain lasting at least two months will receive a single injection of the agent and undergo scans to look for signs of nerve irritation or injury. If a pain-generating nerve is found, they may receive a nerve block and a procedure called cryoneurolysis to temporarily interrupt pain signals. The goal is to see if this imaging approach can guide more precise pain treatments.
