The quality of MWF maps obtained with the standard approach, were compared with results obtained from measured and scaled flip angle maps in a cohort of 10 healthy young volunteers. Two scaling approaches were used; an expected 180 degree pulse and scaling to the first pass fitted FA. The two-step procedure was found to be a viable approach to improve the MWF maps, without a too high cost in terms of goodness-of-fit or distinction between components.
