NCT04399174

Brief Summary

: In this Prospective longitudinal observational study, two hundred pregnant women with singleton pregnancy from 11 up to 13 weeks with history of intrauterine growth restriction in a previous pregnancy underwent ultrasound assessment of gestational age , ultrasound assessment of uterine artery pulsatility index, placental volume by 3D ultrasound and placental vascularization by 3D power Doppler (3DPD).

Outcome Measures

Primary Outcomes (5)

  • placental volume

    Assessment of placental volume.

    11-13 week

  • vascularization index (VI)

    expressed as percentage, measures the number of colour voxels in the studied volume, representing the blood vessels within the tissue

    11-13 week

  • uterine doppler

    uterine artery pulsatility index

    11-13 week

  • flow index (FI)

    the average colour value of all colour voxels, representing average colour intensity.

    11-13 week

  • vascularization flow index (VFI)

    the average colour value of all grey and colour voxels, which represents both blood flow and vascularization

    11-13 week
