Abstract:
The spatial resolution of diffusion-weighted (DWI) images limits the white matter streamline fiber tracks, which can be followed in the brain stem. To address this issue, we introduce a high spatial resolution protocol and the use of a threshold to limit the false positive in streamline track density maps by requiring that a minimum amount of fibers pass through a voxel. This provides increased accuracy in the visualization of streamlines connecting specific regions of the brain stem and may allow the recognition of structural abnormalities due to neurological diseases.
