Intracenter interobserver measurements by time-resolved delineations. Interobserver variability was low in one center but showed high bias in the other center, suggesting that consensus for how to delineate fetal vessels is needed. Bland-Altman plots showing interobserver measurements between observer 1 and 2 (same center) and 3 and 4 (same center) using time-resolved delineations of the fetal descending aorta (DAo) and umbilical vein (UV) using the Doppler-ultrasound (DUS; left) and metric optimized gating (MOG; right) methods. Solid lines indicate bias and dotted lines indicate 95% limits of agreement (LoA)
