In this study, population-based probabilistic connection topographies of the CC, in the standard MNI space, were estimated by incorporating anatomical cytoarchitectural parcellation with high angular resolution diffusion imaging (HARDI) tractography. Using q-ball imaging (QBI) with MFACT algorithm, a more detailed CC subdivision according to 27 selected Brodmanns areas (BAs) was demonstrated. Further, it allowed an assignment of the quantitative distribution of fractional anisotropy (FA) values derived from diffusion tensor imaging (DTI) data of 20 normal healthy subjects to evaluate the correlation with neural composition in distinct CC regions explored by previous postmortem study.
