WebDoppler ultrasound flow studies can be performed serially beginning at 16 to 18 weeks' gestation. Visual representation of the blood flow can be calculated at the time of the procedure by dividing the systolic (S) peak by the end diastolic (D) component. This calculation will yield a systolic/diastolic (S/D) ratio. WebResults: In normal pregnancies, the flow velocity waveforms (FVWs) showed a good diastolic flow and fall in indices as pregnancy progressed. A low diastolic flow and high indices characterized the pregnancies with abnormal outcomes. The uterine artery had a better sensitivity and specificity as compared to the umbilical artery.
