Multi-Shelled QBI (MS-QBI) gives a new orientation distribution function based on the moment of the probability density function. We perform the fiber tracking of human brain based on MS-QBI and confirm the practicability of the method. We implement a simple procedure for streamline fiber trackings of pathways that encounter crossings. The pyramidal tract (PT) can be traced beyond the crossing with the superior longitudinal fasciculus by MS-QBI. The distinction between PT and the corpus callosum in the corona radiata is still difficult.
