# High angular resolution diffusion imaging reveals intravoxel white matter fiber heterogeneity

@article{Tuch2002HighAR, title={High angular resolution diffusion imaging reveals intravoxel white matter fiber heterogeneity}, author={D. Tuch and T. Reese and M. Wiegell and N. Makris and J. Belliveau and V. Wedeen}, journal={Magnetic Resonance in Medicine}, year={2002}, volume={48} }

Magnetic resonance (MR) diffusion tensor imaging (DTI) can resolve the white matter fiber orientation within a voxel provided that the fibers are strongly aligned. However, a given voxel may contain a distribution of fiber orientations due to, for example, intravoxel fiber crossing. The present study sought to test whether a geodesic, high b‐value diffusion gradient sampling scheme could resolve multiple fiber orientations within a single voxel. In regions of fiber crossing the diffusion signal… Expand
