We derived and verified an equation for the theoretical description of longitudinal magnetization for pass- and transition-band bSSFP at steady state. In addition, we show evidence that a DANTE (b-SSFP) preparation module may be employed with an EPI readout to increase negative BOLD response by 12.8% in average (p<0.03) compared to conventional EPI (GE-EPI).
