“…Clinical decision‐making is rarely influenced by Doppler velocimetric indices of the uterine artery (except in cases of preventative treatment started at mid‐gestation), despite their accuracy in predicting unfavorable pregnancy outcome. Abnormalities of uterine blood flow can be detected many weeks before other signs of worsening fetal condition appear9, 10, 14, 33–39. Uterine artery Doppler evaluations in the late third trimester of high‐risk pregnancies have also been shown to be of considerable value in predicting adverse outcome7, 41.…”

Objective-To assess the screcning propertics of a mid-trimester uteroplacental Doppler scan in a normal unselectcd population. Design-A cross-sectional study measuring an averaged resistance index (AVRI) from four sites (left and right uterine and arcuate arteries) with continuous wave Doppler ultrasound. Setting-Rout ine booking ultrasound, King's College Hospital, London. Subjects-977 women at 16-24 weeks gestation. Mairi outcome measures-Intrauterine death, birthweight, pregnancy-induced hypertension (PIH), antepartum haemorrhage. Results-There was a 96.5% follow-up. Pregnancies with high AVRI values had a higher prcvalence of proteinuric hypertension, placental abruption, small-forgestational-age babies, and fetal loss. When AVRI was >95th centile, the ovcrall risk of pregnancy complications was 67%, and the risk of a severe complication was 25%. However, the sensitivity of the test for these complications was only 13% and 21% respectively. The risk for an individual woman with a high AVRI of developing a complication was increased by up to 9.8 times. Conclusion-Although Doppler screening does detect a unifying defect leading to perinatal death, pre-eclampsia, growth retardation and placental abruption, the predictive values do not yet justify its introduction as a routine test.

Purpose: To measure uterine artery and vein blood velocity and flow rate profiles using MRI during normal pregnancy. Materials and Methods:A two-shot velocity magnitudeencoded echo planar imaging (EPI) sequence is used at a magnetic field 0.5T. Data analysis procedures, necessary to overcome problems associated with low signal to noise ratio (SNR), and a spatial resolution comparable to the vessel size were used. Results:The measured blood flow values averaged over nine volunteers for the mean velocity are 5.33 and 3.97 cm/s and for the unilateral flow rate are 203 and 274 mL/min (for the arteries and veins respectively). Values for the flow rate are consistent with ultrasound Doppler studies. Arterial velocity measurements are more pulsatile than venous ones and validation calculations performed on average velocity values would suggest that the nature of blood flow in the uterine vessels is laminar. Conclusion:This study presents the first report of noninvasive quantitative measurements of uterine artery and vein blood velocity and flow rate profiles using MRI during normal pregnancy. Consistent and reproducible measurements have been obtained by subject specific sequence optimization and data analysis procedures.
