Keywords: Flow, Cardiovascular, compressed sensing, real-time imaging, phase-contrast MRIHighly-accelerated real-time phase-contrast (rt-PC) using compressed sensing may underestimate (~17%) velocity measurements due to over regularization. We sought to address this underestimation by incorporating view-sharing (VS) and k-space weighted image contrast (KWIC) filtering. This is particularly important for pediatric patients who have faster heart rates and smaller hearts than adults, it is particularly important to achieve high temporal resolution. The proposed reconstruction achieves 25 ms temporal resolution without significant temporal blurring artifacts.
