DOI: 10.1002/mrm.29286
Abstract: Myelin water fraction (MWF) is often obtained from a multiple echo spin echo (MESE) sequence using multi‐component T2 fitting with non‐negative least squares. This process fits many unknowns including B1+ to produce a T2 spectrum… read more here.

DOI: 10.1111/jon.12659
Abstract: Acquiring and interpreting quantitative myelin‐specific MRI data at an individual level is challenging because of technical difficulties and natural myelin variation in the population. To overcome these challenges, we used multiecho T2 myelin water imaging… read more here.
