This study shows the feasibility of 1D Diffusion Weighted Spectroscopy in an array along a specific fiber tract that was visualized on the fly using Diffusion Tensor Imaging with fiber tracking. This approach could be used to measure difference between parallel and perpendicular diffusion of various metabolites in specific fiber tracts.
