Four-Dimensional Spectral-Spatial Pulse for Fat Saturation with Parallel Excitation: Preliminary Results on 3T Scanners

Feng Zhao¹, Jon-Fredrik Nielsen¹, Douglas C. Noll¹

Fat saturation techniques that use spectrally selective pulses suffer from inaccurate excitation due to inhomogeneous B0 or B1 maps. To solve this problem, wee propose a 4D spectral-spatial pulse with parallel excitation, which is demonstrated by preliminary 3T data.
