ABSTRACT

We compared the diffusion tensor distribution parameters to microstructure features in realistic, simulated substrates in diffusion MRI. The orientation parameter is related to the actual angular dispersion of white matter fibers; extra-axonal signal reveals complex, non-Gaussian diffusion.
