Probabilistic Anatomical Connection Derived from QBI with MFACT Approach

Recently developed methods to resolve multiple fiber orientations within a voxel from high angular resolution diffusion imaging (HARDI) are applied to resolve complex neuronal connectivity. In the study, an extension of multiple streamline tractography was proposed to estimate the probabilistic fiber tracking between brain areas. Multi-fiber component in the conjunction of corticospinal tracts, corpus callosum, and superior longitudinal fasciculus were studied in this study. The extracted results from probabilistic tracking presented the potential to estimate the whole brain map of anatomical connection probability.
