Metabolism in the Human Brain Following Consumption of a Keto-ester in Alcohol Use Disorder (AUD) With Proton Magnetic Resonance Spectroscopic Imaging (MRSI)

Following baseline scans, the participant will orally consume the keto-ester, for subsequent scans which will include repeated BHB MRSI acquisitions to dynamically measure BHB labeling in the brain, followed by a final GABA MRSI acquisition.
