The Impact and Reliability of Tissue Segmentation on In Vivo Magnetic Resonance Spectroscopy Metabolite Quantification

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...

Hippocampal subfield differences in people with and without recreational ketamine use: Insights from multi‐modal neuroimaging

Addiction, EarlyView.
Abstract Background and aims Recreational ketamine use has increased globally and is associated with psychiatric and cognitive concerns. The hippocampus in preclinical models shows damage and working‐memory disruption with repeated dosing. However, whether specific hippocampal subregions may differ in people with chronic ketamine use remains unclear ...

Associations of cannabis use, tobacco use and co‐use with brain volume: A systematic review and meta‐analysis

Addiction, EarlyView.
Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Diagnostic validity of Addictions Neuroclinical Assessment indices for alcohol use disorder: Findings from an observational case–control study

Addiction, EarlyView.
Abstract Background and aims The Addictions Neuroclinical Assessment (ANA) provides a framework for assessing alcohol use disorder (AUD) with indices that may be both mechanistically and diagnostically informative. This study evaluated an array of measures from the three ANA domains in relation to AUD diagnostic status. Design This cross‐sectional case–
