Visualizing Crossing Fibers

Diffusion MRI can provide information on the organization of neuronal tissue in vivo. Based on these images, fiber tract pathways can be reconstructed that represent the axonal wiring of the brain. Anatomical knowledge lets us select specific fiber bundles connecting two brain regions, in this case the arcuate fasciculus connecting two areas involved in language processing. Visualization of all fiber tracts crossing such a fiber pathway can be informative to show the large-scale connectivity, but obscures the pathway of interest. By reducing these crossing fiber tracts to local representations, it becomes possible to visualize the complex tissue architecture locally along a fiber tract in a compact and elegant manner.
