Fig 1. A, An example of coregistration across 3 protocols. Images on the left, middle, and right are obtained with the 6-NDGD, 21-NDGD, and 31-NDGD protocols, respectively. A region of interest (ROI) of the splenium of CC is initially drawn on only 1 image from 1 of the 3 protocols and then translated to the corresponding images from the other 2 protocols.

B, Spatial definition of ROIs: all ROIs are positioned relative to CC in the anterior (A, CCA), middle [B, CCM, cingulum (D), SLF (E), and IC (F)], and posterior [C, CCP, cingulum (D), and SLF (E)] locations.
