Along-Tract Microstructural Alterations Associated with Stimulant Misuse Localized using Diffusion MRI Tractometry
This study demonstrates that applying segment-wise along-tract 3D tractometry to diffusion MRI reveals focal, reproducible white matter microstructural alterations in specific hippocampal and commissural pathways associated with stimulant misuse, offering superior anatomical specificity compared to traditional whole-bundle analyses.
