Doppler velocimetry has recently become an informative procedure for the real-time and noninvasive evaluation in fetal hemodynamics. The analysis of flow velocity waveforms in various kinds of vessels has been made for not only clarifying fetal physiology and pathophysiology of various disorders but also for determining the most appropriate intervention from the viewpoint of the integrated management protocol. The unique change in both the arterial and venous flow in normal and compromised fetuses has been demonstrated. Clinical applications of the Doppler technique in monitoring the fetus are reviewed.
