Fiber Tracking-MRI

Diffusion tensor imaging is unique in its ability to non-invasively visualize white matter fiber tracts in the human brain in vivo. Diffusion is the incoherent motion of water molecules on a microscopic scale. This motion is itself dependent on the micro-structural environment that restricts the movement of the water molecules. In white matter fibers there is a pronounced directional dependence on diffusion. With white matter fiber tracking projections among brain regions can be detected in the three dimensional diffusion tensor dataset according to the directionality of the fibers. This is a case of glioma shown with fiber tracking.
