Matched Phase Dualband Spatial-Spectral 90-180 Pulse Pair for MRSI at 3T
Balchandani P, Spielman D, Pauly J
A pulse sequence has been designed for use at 3T that utilizes a dualband spatial-spectral matched phase 90-180 pulse pair to excite a thin slice. The sequence enables shorter echo times while still having a spectrally selective profile that suppresses lipids and partially suppresses water. In addition, the pulse pair is designed so that the final echo has completely flat phase. Results of phantom studies show successful suppression of all resonances outside the metabolite passband.
