The pulse diagrams of double-refocused hyperbolic secant (DRHS) velocity-selective saturation (VSS) pulse (DRHS-VSS)), symmetric BIR8 VSS (sBIR8-VSS) pulse, the original VSI pulse using hard RF pulses of the same small flip angles (rect-VSI), a modified VSI pulse with a regular sinc-shaped inversion pulse of 9 segments (segmented-sinc-VSI), a modified VSI pulse with a maximum-phased sinc modulation on the amplitude of the small flip-angle pulses (mp-sinc-VSI), and the modified VSI pulse with a regular sinc modulation (sinc-VSI).
