Doppler-ultrasound (DUS) versus metric optimized gating (MOG) flow volumes. The DUS versus MOG comparison showed low bias and wide limits of agreement between methods. Bland-Altman plots showing intermethod agreement for flow volume quantification in the descending aorta (left) and umbilical vein ( right) using time-resolved (top) and static (bottom) delineations, respectively. Solid lines indicate bias and dotted lines indicate 95% limits of agreement (LoA)
