Zusammenfassung
Sodium triple-quantum-filtering (TQF) is challenging at ultra-high field due to the high specific absorption rate. In order to alleviate this problem, the feasibility to modulate the flip angle of the TQ preparation along the partition-encoding direction was investigated. As demonstrated by simulations, this approach allowed to increase the efficiency and sensitivity of the TQ acquisition. TQF images of the human brain could be acquired at 9.4 T within 20 min with an acceptable signal-to-noise ratio.
