Flow-velocity waveforms in the fetal renal artery. A: Type I (absence of diastolic flow in the entire cardiac cycle) at 15 weeks (systolic waveform is visualized). B: Type II (absence of diastolic flow at the end of cardiac cycle) at 20 weeks (the systolic waveform is present and the diastolic waveform is absent). C: Type III at 24 weeks (systolic waveform is present and the diastolic waveform progresses into the following systolic waveform).
