We explored the application of acquiring Fourier Velocity Encoding (FVE) without spatial encoding to quickly estimate the velocity distribution within a volume of interest. One application is to allow for quick selection of Venc for a subsequent 4D-Flow acquisition, which can limit velocity aliasing and fine-tune the velocity-to-noise ratio for better data quality. Other applications may include new ways of looking at the pulsatility or turbulence of a volume of interest. In this work we implement a FVE sequence in Pulseq and run it in flow phantoms to demonstrate the proof-of-concept data of this technique.
