Summary

Preliminary data will be obtained in cocaine-addicted subjects who are actively using cocaine and those who are recently abstinent (three to six months abstinent) as well as age-, race-, and gender-similar control participants (matched to active cocaine subjects). Ten recently using and ten recently abstinent cocaine-addicted and ten age-, race-, gender similar healthy control subjects will each undergo one 3T scan at the AIRC. Each scanning session will consist of Magnetic Resonance Spectroscopy and Vascular-Space-Occupancy imaging scans to measure the number of NPCs in the brain. Each session will last approximately one hour. Data from each session will be sent to Dr. Maletic-Savatic at Baylor College of Medicine in Houston for analysis.
