FIG 1. Image data sets for calculating GM and WM MTRs by using the image-processing program.
A and B, Dual-echo FSE proton density–weighted (A) and T2-weighted (B) images.
C and D, Images obtained with the MT saturation sequence off (C) and on (D).
E and F, Segmented volume image of GM (E) and WM (F) were generated from original proton density–and T2-weighted images.
