The purpose of this study was to measure the inter-scanner reproducibility of fast myelin water fraction (MWF) mapping using a 4 min FAST-T2 sequence on three scanners from two vendors at 1.5T and 3T. Regional MWF measurements obtained in 7 healthy volunteers were highly reproducible with excellent inter-scanner correlation (R>0.95) and small MWF bias of less than 1%.
