View-sharing PROPELLER (VS-Prop) with a pixel-based optimal blade selection (POBS) algorithm has been proposed to shorten the acquisition window during dynamic contrast imaging, leading to a higher spatiotemporal resolution or/and spatial coverage. In this work, flow phantom experiment was performed to evaluate the temporal and spatial accuracy. In addition, the result of first-pass dynamic contrast-enhanced (DCE) cardiovascular imaging on healthy volunteers was also presented.
