Uterine artery flow velocity waveform (FVW) type and subednometrial vascularity in recurrent pregnancy loss.

To assess the subendometrial and uterine artery blood flow and pattern of the waveform of the uterine artery in cases of recurrent pregnancy loss compared with normal controls. Fifty women with a history of two or more successive pregnancy losses were investigated by Doppler transvaginal ultrasound to assess the subendometrial blood flow resistance index (RI), type of Doppler waveform of the uterine artery, and uterine artery pulsatility index (PI) in the mid-luteal phase. Fifty normal women acted as controls.

Value of three dimensional power Doppler ultrasound in prediction of endometrial carcinoma in patients with postmenopausal bleeding.

Objective: To determine whether endometrial volume or power Doppler indices measured by 3-dimensional (3D) ultrasound imaging can discriminate between benign and malignant endometrium in women with postmenopausal bleeding and endometrial thickness ≥5 mm.

Material And Methods: The current diagnostic accuracy study was conducted at Ain Shams University Maternity Hospital. Eighty-four patients with postmenopausal bleeding and endometrial thickness ≥5 mm underwent 3D power Doppler ultrasound examination of the corpus uteri.
