An adiabatic T2prep design based on the modified BIR-4
pulse is proposed for multicomponent T2 relaxometry of
the brain at 3T. When compared to the conventional
composite refocusing T2prep, our results show that the
proposed BIR-4 design provides more accurate T2
weighting against increased field inhomogeneities at 3T,
enabling fast and reliable whole brain myelin water
mapping in 10 minutes.
