Pulse sequence schemes used in the current study. (a) Gradient-Echo EPI (b) Spin-Echo EPI (c) Hybrid SPEN [12] (d) Spatiotemporally-encoded RASER [11]. In both (c) and (d) the excitation is replaced with a frequency-swept pulse, while slice-selection is performed using 180° selective pulses. Abbreviations denote: exc excitation, acq acquisition, RF irradiation channel, RO readout channel, PE/SPEN phase- or SPEN-encoded channel, SS slice-selection channel, ADC signal acquisition channel, Npe number of phase/spatiotemporally-encoded lines.
