ClinConnect Summary

Abnormalities in the re-uptake of dopamine and serotonin have been described in various neuropsychiatric disorders and substance abuse. \[I-123\] Beta-CIT is a recently developed radioligand for SPECT imaging of dopamine and serotonin transporters. \[I-123\]Beta-CIT SPECT has been used at the SPECT-Lab of the Clinical Brain Disorders Branch in over fifty subjects without adverse events. Due to the trace concentrations used, a pharmacological effect of Beta-CIT is unlikely and has not been observed. The purpose of this study is to use Beta-CIT and SPECT to study the expression of dopamine an...
