Flow diagram of WM network construction applying DTI based on BNA-246 atlas. (1) b0 image (A) in the individual diffusion space for each participant was aligned with the T1-weighted image (B). (2) The co-registered T1-weighted image of the native DTI space was mapped to the nonlinear ICBM152 T1 template (E) of the MNI space using a nonlinear transformation matrix T. (3) Warped the BNA-246 atlas (C) in MNI space into the native diffusion space (F) by inverting T1 format T− 1. (4) Whole-brain WM fibers (D) were traced with DTI tractography employing the deterministic tractography algorithm. (5) The whole brain WM network was constructed in patients with CD and HCs. FSe-weighted matrices (G) for CD and HCs groups.
