Trial ID or NCT#
Chronic pain can result from injured or inflamed nerves, as occurs in people suffering from sciatica and CRPS. These nerve injuries or regions of nerve irritation are often the cause of pain in these conditions, but the current diagnostic tools are limited in pinpointing the area of origin. Several studies have implicated involvement of sigma-1 receptors in the generation and perpetuation of chronic pain conditions, others are investigating anti sigma-1 receptor drugs for the treatment of chronic pain. Using the sigma-1 receptor (S1R) detector and experimental radiotracer [18F]FTC-146 and positron emission tomography/magnetic resonance imaging (PET/MRI) scanner, the researchers may potentially identify the source of pain generation in patients suffering from complex regional pain syndrome (CRPS) and chronic sciatica. The ultimate goal is to assist in the optimization of pain treatment regimens using an [18F]FTC-146 PET/MRI scan. The study is not designed to induce any physiological/pharmacological effect.
