Patterns were similar for the systolic/diastolic (S/D) ratio and the pulsatility index (PI) (Figure 3C, D; see also Table S1), which are additional indicators of resistance.
11] Several workers have measured the peak systolic/end diastolic ratio (S/D), pulsatility index (PI), and resistance index (RI) in the uterine artery only.
Analysis of Umbilical Artery Doppler Velocimetry Umbilical Artery Pulsatility Index
Rowland and Vyas found that reversal of adaptation in fetal hypoxemia as indicated by rise in MCA pulsatility index may be a predictor of IUD within 48 h.
Bilateral peak-systolic, end-diastolic, and mean blood flow velocities in the MCA, pulsatility index values, and resistance index values were recorded.
The predictive role of doppler velocimetry was based on the differences found in mean uterine artery pulsatility index (PI), resistance index (RI) and peak systolic velocity (PSV), systolic/diastolic velocity ratio (S/D) values between pregnant and nonpregnant groups of women.
The systolic/diastolic ratio (S/D), pulsatility index (PI), and resistance index (RI) are the hemodynamic indices of the fetoplacental circulation.
The study was conducted prospectively to evaluate the influence of transplacental needle passage on uterine artery (UtA) pulsatility index (PI) resistance index (RI); umbilical artery (UA) PI and RI; ductus venosus (DV) PI and RI; fetal mid-cerebral artery (MCA) PI and RI.
Results show that placental volume and uterine artery pulsatility index (PI) are independent predictors of SGA at mid-pregnancy.
47,48) It can evaluate the vascular pattern, displacement of vascularity, vascular resistance, and pulsatility index.
