Reproducibility and intercorrelation of graph theoretical measures in structural brain connectivity networks

Diffusion-weighted (DW1) magnetic resonance imaging (MRI) can be used to noninvasively investigate the microstructural properties of the brain. Diffusion in fiber tracts is anisotropic, i.e. larger parallel to the tract than perpendicular to it, which enables the reconstruction of neural pathways in the brain with fiber tracking  [9,38]. Diffusion tensor imaging (DTI) is traditionally the most common method used for the analysis of DW-MRI data [7,8]. However, its major limitation is the inability to correctly describe complex fiber configurations such as crossing fibers, present in the majority of white matter (WM) [40,8 2].
