A novel approach is presented to indirectly image brain
myelin content. The proposed method is based on a pulsed
saturation transfer experiment, in which water with
short T
2
(including
myelin water) is selectively saturated, after which the
delayed effect on long T
2
water
is studied. Experiments performed at 7T confirm
sensitivity and specificity of the method.
