Flowchart of structural network construction using diffusion MRI data. (A) Diffusion tensor imaging (DTI) data acquisition. (B) Reconstruction of white matter (WM) fiber tracts using deterministic tractography. (C) Whole-brain parcellation into 90 nodes according to the Anatomical Automatic Labeling (AAL) atlas. (D) Structural connectivity matrix construction by assigning reconstructed fibers to corresponding nodes. (E) Example of a structural network representation from a healthy subject. (F) Comprehensive analysis of the resulting structural network. Abbreviations: WM, white matter; FA, fractional anisotropy; AAL, Anatomical Automatic Labeling
