Keywords: White Matter, Diffusion/other diffusion imaging techniquesThis study aimed to explore the changes of brain white matter changes in short-term methamphetamine (MA) abstinence and to investigate potential imaging markers. Compared with healthy controls (HC), fractional anisotropy (FA), axial diffusivty (AD) and mean diffusivity (MD) values in short-term abstinence group were all increased, but there was no significant difference in the radial diffusivty value. The changes of FA, AD and MD value may be a new biomarker which is helpful to explore the potential mechanism of neurotoxicity damage.
