This protocol will investigate the neurobiological underpinnings of alcohol craving in recently detoxified alcoholic drinkers utilizing novel functional brain imaging. This clinical magnetic resonance spectroscopy (MRS) study will investigate whether glutamate and other brain metabolites correlate to measures of alcohol craving severity
Utilizing Magnetic Resonance Spectroscopy at 3 Tesla, investigate the neurobiological underpinnings of alcohol craving
assessing baseline perturbations in anterior cingulate and ventral striatal metabolites (NAA levels, glutamate levels, glutamine levels)
Secondary Outcome Measures :
Evaluate the relationship between these metabolites, each reported as a Cerebrospinal Fluid-corrected absolute concentration, and severity of alcohol cravings
Evaluate the relationship between these metabolites, each reported as a Cerebrospinal fluid-corrected absolute concentration, and severity of alcohol cravings, as measured primarily by the Penn Alcohol Craving Scale and secondarily by the Inventory of Drug Taking Situations.

History of claustrophobia
History of major head trauma with loss of consciousness >5 minutes or skull fracture
History of previous neurological event (e.g. epilepsy, stroke, transient ischemic attack)
