The effectiveness of using adiabatic, on resonance, 3600
pulses for myelin water imaging based on pulsed
saturation transfer contrast is evaluated. Using
multi-component analysis of T2* signal decay at 7T, we
demonstrate that adiabatic, on-resonance, 3600 pulses
allow a strong (80%) saturation of myelin water, while
effects on axonal and interstitial water can be kept
below 25%. This high selectivity greatly facilitated
saturation transfer kinetics and the visualization of
myelin water content.
