White matter T1 values have been reported to range from 699ms-1735ms1. The recently introduced Controlled Saturation Magnetization Transfer (CSMT)2 qMRI approach suggests this might be due to MT effects. In this work employ the CSMT framework on 3 major MR manufacturers and demonstrate it allows a decrease in variability of T1/T2 estimation both in phantom and in-vivo.
