文摘
- •
We propose a method to estimate anisotropic orientation dispersion of neurites.
- •
Estimation of this anisotropy enhances tractography and is a potential marker of disease.
- •
The method uses NODDI, a clinically feasible technique to estimate neurite morphology.
- •
We show that the estimation of indices of the proposed model is clinically feasible.
- •
The new model explains the data better in white matter compared to the original model.
