Diffusion-weighted imaging (DWI) is a technique that can be used to visualize neural tracts or nerve fibre bundles by measuring the direction of water diffusion in brain tissue. The example figure below shows a so-called connectome — the structure of nerve fibre pathways in the brain — estimated from the DWI data of a single individual. The red horizontal lines in the center of the image show the corpus callosum, the bridge between the two brain halves. The blue vertical lines in the lower center of the image show the corticospinal tract, where the brain is connected with the nervous system in other parts of the body. The provided scans have been made with a standard clinical procedure at 2 mm spatial resolution. For more more information on this image type, see Wikipedia. The complete description of this acquisition has been published in:
