Why the study?
Does the use of an endovaginal ultrasound transducer improve the reproducibility of uterine artery pulsatility index measurements compared to transabdominal transducers?

Endovaginal probes yield reproducible uterine artery PI values differing from transabdominal; leaves open optimal technique standardization in practice and trials.
Does the use of an endovaginal ultrasound transducer improve the reproducibility of uterine artery pulsatility index measurements compared to transabdominal transducers?
Transvaginal colour Doppler ultrasound provides reproducible and reliable measurements of uterine artery impedance compared to transabdominal approaches.
