An interactive real-time velocity encoding (venc) scout is introduced as a fast and easy way to optimize the parameters of a clinical flow measurement. The required image quality and frame rate in the phase contrast images is achieved by applying severely undersampled radial acquisition. The interactively found venc value and scan plane geometry are propagated automatically to the subsequent clinical segmented flow measurements. The method is compared against a standard segmented breath-hold venc scout.
