Repeated flow acquisitions in six fetuses. The Doppler ultrasound gating method showed generally high repeatability. Measurements from repeated flow acquisitions in the descending aorta (closed circles) and umbilical vein (open circles) in six subjects. Flow acquisitions were acquired six to 12 times in each vessel. In subject 6 umbilical venous flow was not successfully acquired due to early termination of the CMR examination. Solid lines indicate medians
