Diffusion tensor MRI (DTI) has shown its feasibility in white matter connectivity. In this study, a probabilistic connectivity atlas was presented with the tract-based transformation into MNI152 space. The white matter tractography was based on FACT (fiber assignment by continuous tracking) algorithm with fractional anisotropy (FA) threshold of 0.2 and angular threshold of 60 degrees. By calculating the neural bundles in MNI152 coordinate, the probabilistic tract atlas was regarded as a new template which can provide the correct location of neural bundles. The results can facilitate further studies on neural connectivity, brain mapping, and diffusion indices analysis for clinical applications.
