Abstract:
The exchange weighting and robustness to B 0 -inhomogeneities are essential properties for accurate
CEST-MRI saturation measurements. Therefore, we investigated these properties for a new numerical
optimized saturation pulse train and for state-of-the-art saturation pulse strategies in simulation
and phantom measurements. We have found that the optimized pulse train generates superior CEST
contrast and has very high stability against B0-inhomogenities while maintaining the natural shape
at the water peak which improves CEST-spectrum fitting and B 0 -correction.
