A magnetic resonance imaging scanner acquires diffusion-weighted imaging data. A reconstruction engine reconstructs the acquired diffusion-weighted imaging data into diffusion-weighted image representations. A diffusion tensor engine constructs a diffusion tensor map of an area of an interest of a subject. An eigenvalue/eigenvector ordering engine obtains and orders eigenvectors and eigenvalues at each voxel. A covariance matrix determining engine constructs a covariance matrix of a major eigenvector of each voxel. A first normalized measure determining engine computes a first normalized measure. A second normalized measure determining engine computes a second normalized measure. A rendering engine generates a human-viewable display of an image representation.
