Ultra high field MRI time-of-flight angiograms can often be seriously degraded by pulsation artifacts. A method based on random order sampling, retrospective gating and L1-SPIRiT reconstruction was developed and tested on a 7 T scanner. The results confirmed that the proposed method can reduce the flow artifacts.
