2 Fig. 1 Diagram shows how the diastolic/systolic ratio for each arterial waveform was calculated from the ratio of the end-diastolic velocity (EDV) to the peak systolic velocity (PSV).

3 Fig. 2 A, Normal (low resistance) Doppler spectral waveform obtained from the renal parenchyma. Note that the end-diastolic velocity is relatively high in comparison with the peak systolic velocity, and the diastolic/systolic ratio is normal at B, Abnormal (high resistance) Doppler spectral waveform. The end-diastolic velocity is relatively low, with a diastolic/systolic ratio of 0.23.
