In
this study, we investigated the relationship between the effect of alcoholic
use and the microstructural alteration of seven association fiber tracts
using diffusion spectrum imaging tractography and tract-specific analysis.
The metric of generalized fractional anisotropy (GFA) was used to identify
the difference between control and alcoholic groups. Among all the
association fiber tracts, a significant GFA deficit was found in bilateral
superior longitudinal fasciculus for chronic alcoholics. A future study to
analyze the segmented parts of the tract is needed to further reveal the
subtle change of microstructural alteration of association fiber tracts in
alcoholism.
