Flow volumes and flow differences between methods versus gestational age. The graphs show flow volumes obtained using time-resolved delineations without background correction versus gestational age for the Doppler ultrasond (DUS) and metric optimized gating (MOG) methods in the descending aorta (top left) and umbilical vein (top right) and the percent difference in flow between the DUS and MOG methods versus gestational age for the descending aorta (DAo; bottom left) and umbilical vein (UV; bottom right)
