This digitally enhanced axial (cross sectional) image was obtained from a special MRI sequence called diffusion tractography (DTI for short). This technique allows us to map out the directionality of white matter fiber tracts in the brain by exploiting the preferential movement of water (protons) parallel to the direction of these white matter tracts (called anisotropic diffusion). Color coding by conventional uses red for right to left, green for anterior to posterior and blue for superior to inferior directions of the tracts. This technique can be used to study the effects of white matter diseases on the fiber tracts and can also aid the neurosurgeon for preoperative planning by showing where certain important tracts are located in the area of surgery.
