Official title
Use of SPECT (Single-photon Emission Computed Tomography) to Examine the Role of DAT (Dopamine Transporter) Genotype in Motivated Smoking Behavior
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
A polymorphism in the dopamine transporter (DAT) may determine how much dopamine is available at the synapse and this may affect the underlying reasons for relapse in smokers. This research will use Single-photon emission computed tomography SPECT and the DAT-specific ligand, TRODAT (Dopamine Transporter Density by \[99mTc\]), to examine the availability of DAT in smokers grouped by genotype in the sated (just having smoked) and withdrawal (4 hours without smoking) conditions.
