| Zusammenfassung | In this work, we investigate the feasibility of velocity encoded/compensated asymmetric multi-spoke RF pulses. Bloch simulations, phantom studies, and in-vivo measurements are conducted to characterize the pulse performance. Compared to conventional multi-spoke RF pulses, the results indicate that asymmetric multi-spoke RF pulses are suitable for both 2D and 3D acquisitions and can significantly reduce the repetition time without compromising on velocity quantification. The hereby gained acceleration can be additionally combined with techniques such as GRAPPA or compressed-sensing to further decrease the total acquisition time.
