In this study, a novel RF-based water-fat separation method is introduced, by utilizing the unique frequence response profile of a pair of opposite-phase rectangular pulses.Functioning as simutaneous excitation and selective suppression, the dual-rect pulses do not require extra scan time but come with low SAR level. With the simplicity and robust performance due to the broad passbands and stopbands, our method is especially advantageous for high field fast 3D imaging.
