Mid-trimester uterine artery Doppler screening as a predictor of adverse pregnancy outcome in high-risk women. Intrauterine growth retardation—a prospective study of the diagnostic value of real-time sonography utefinas with umbilical artery flow velocimetry. Rizzo, A-L Tranquilli, G. Transvaginal color Doppler assessment of uteroplacental circulation in normal and abnormal early pregnancy. In our study, as individual measurements, abnormal RI from umbilical artery, and altered PI from umbilical and middle cerebral arteries, were associated to PE; however, considering all the parameters reviewed in these arteries, the general results for each vessel did not show a difference between groups, suggesting that these individual parameters, but not the general Doppler US for these arteries, could be considered as indicators to evaluate the specific PE vascular alterations.
