Segmentation of basal ganglia structures and fiber tracking between basal ganglia segmentations for comparing diffusion measures such a between controls and Parkinson's disease patients shows potential biomarkers for diagnosing PD. 
Figure 1. Results of MNI PD25 atlas segmentation using Lead-DBS SPM and ANTs co-registration, normalization. Left shows the 22 structures in 3D models overlaid on top of an example subject’s b0 FA image.
Figure 2. Connectivity matrices of significant differences in qa, fa, md, ad, rd of MNI PD25 basal ganglia structure interconnectivity. Left column represents connectivity matrix of mean differences in qa, fa, md, ad and rd diffusion measures. Middle column represents p-values of student t-tests done for every connectivity matrix pair with significance at p < 0.05. Right column represents the adjusted p-values of t-tests using Benjamin-Hochberg procedure with p < 0.2.
