Summary

Preclinical work suggests that D3 dopamine receptors may be important in the study of the pathophysiology of affective disorders, psychotic disorders and addiction. D3 receptors may also play a role in dystonia, Parkinson's disease and response to treatment of these disorders. However, there has been a lack of specific radioligands for imaging D3 receptors. This proposed protocol will evaluate the uptake of \[18F\]FTP as a more specific in vivo measure of D3 receptor binding in the brain in healthy volunteers subjects after injection of lorazepam vs placebo, and in cocaine-dependent subjects. Test-retest scans will evaluate the variability of \[18F\]FTP uptake measures in both healthy volunteer subjects and cocaine-dependent subjects.

Conditions

  • D3 Dopamine Receptor
  • Cocaine-dependent
  • Healthy Volunteer

Interventions

DRUG

[18F]FTP PET/CT

All PET/CT imaging sessions will include an injection of \[18F\]FTP. Pilot data will be collected to evaluate preliminary information on brain uptake of \[18F\]FTP in healthy volunteers and cocaine-dependent volunteers.
