Magnetic Resonance Spectroscopy Probe Study of Alcohol Use


Rochester, Minn.

Trial status:

Open for Enrollment

Why is this study being done?

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
