Figure 1. Example of Tissue Processing for the CVR Analysis: NAWM Mask in a Participant's T2W Space.

Figure 1

(A) NAWM mask (red mask) before processing. (B) The original NAWM mask (red mask) was eroded by 1 mm in all directions, and voxels within the dilated mask of the ventricles (blue mask) were removed. (C) The final NAWM mask (red mask) before registration to the participant's mean BOLD space. BOLD = blood oxygen level-dependent; NAWM = normal-appearing white matter.
