“…7 Again, percentiles of the ranked PI measurements in the second trimester have been associated with adverse pregnancy outcome in twins. 14 However, this has not been confirmed in singletons, 11 though one study discussed lowest PI to be more sensitive for preeclampsia in singletons. 10 As well as, mean RI values 8 combination of Resistance Index (RI) measurements and the assessment of diastolic notches have been shown to predict pregnancy-induced hypertension and fetal growth restriction better when performed at 20 weeks.…”

“…In PE, impaired remodelling of the spiral arteries leads to reduced uteroplacental arterial flow [4]. Uterine artery Doppler examination is used in clinical practice as a surrogate for trophoblastic invasion and placental perfusion and has been proposed as a screening tool for PE with several large studies showing a detection rate of up to 80% for pre-term PE [10,11,12,21,22,23]. …”

The aim of this study was to compare time-domain waveform analysis of second-trimester uterine artery Doppler using the resistance index (RI) with waveform analysis using a mathematical tool known as wavelet transform for the prediction of pre-eclampsia (PE). This was a retrospective, nested case-cohort study of 336 women, 37 of whom subsequently developed PE. Uterine artery Doppler waveforms were analysed using both RI and waveform analysis. The utility of these indices in screening for PE was then evaluated using receiver operating characteristic curves. There were significant differences in uterine artery RI between the PE women and those with normal pregnancy outcome. After wavelet analysis, significant difference in the mean amplitude in wavelet frequency band 4 was noted between the 2 groups. The sensitivity for both Doppler RI and frequency band 4 for the detection of PE at a 10% false-positive rate was 45%. This small study demonstrates the application of wavelet transform analysis of uterine artery Doppler waveforms in screening for PE. Further prospective studies are needed in order to clearly define if this analytical approach to waveform analysis may have the potential to improve the detection of PE by uterine artery Doppler screening.

This is the accepted version of the paper.This version of the publication may differ from the final published version. Permanent repository link ConclusionThis study demonstrates that in the majority of early third trimester pregnancies, the uterine arteries can be identified, and their flow profiles measured using MRI, and that the derived PI and RI values are comparable with Doppler ultrasound values.MRI may prove a useful future technique to complement the use of ultrasound in the assessment of fetal well-being.3
