Brain fibres, tract density imaging. Axial scan of the brain showing the density of nerve pathways (tracts) in the brain. The image was obtained using 3D diffusion tensor imaging (DTI) magnetic resonance imaging (MRI) scans. The fibres are locally coloured red-green-blue if they are orientated in x-y-z alignment (left-right, posterior-anterior, inferior-superior). Diffusion tensor imaging measures the direction of water diffusion, which in the brain reveals the orientation of nerve fibres. The technique is also known as tractography, producing a tractogram.
