The objective was to develop fast and reproducible whole
brain myelin water mapping for longitudinal study of
multiple sclerosis. A 4 min Fast Acquisition with Spiral
Trajectory and T2prep (FAST-T2) sequence together with a
robust multi-voxel Spatially constrained Nonlinear
(SPAN) data fitting algorithm enabled highly
reproducible myelin water fraction measurements between
repeated scans (negligible bias with
limits of agreement on a per voxel basis).
