Follicular and endocrine profiles associated with different GnRH-antagonist regimens: a randomized controlled trial.

This trial assessed the impact of early initiation of gonadotrophin-releasing hormone (GnRH) antagonist on follicular and endocrine profiles compared with the fixed GnRH-antagonist protocol. Eighty-five oocyte donors were randomized to GnRH antagonist starting in the mid-luteal phase of the prestimulation cycle (degarelix-ML group), on stimulation day 1 (early follicular phase, degarelix-EF group) or day 6 (fixed protocol) (mid-follicular phase, ganirelix-MF group). Subjects in the degarelix-EF and ganirelix-MF groups received placebo in the prestimulation cycle.

Adnexal torsion: color Doppler and three-dimensional ultrasound.

Objective: To correlate preoperative ultrasound and color Doppler findings in patients with surgically proven adnexal torsion.

Materials And Methods: A 5-year retrospective study included 36 patients with acute lower abdominal and/or pelvic pain. Twenty-four patients had complete adnexal torsion followed by adnexectomy.

2D and 3D hysterosalpingo-contrast-sonography in the assessment of uterine cavity and tubal patency.

Objective: To demonstrate the diagnostic efficacy of 2D B-mode, color and pulsed Doppler Hy-Co-Sy and 3D B-mode and power Doppler Hy-Co-Sy.

Study Design And Methods: One hundred and fifty-two women were recruited into the 2D B-mode, color and pulsed Doppler Hy-Co-Sy study and 116 other women were recruited into the 3D B-mode and power Doppler Hy-Co-Sy study. We assessed the diagnostic performance (sensitivity, specificity, PPV and NPV) of 2D and 3D Hy-Co-Sy, compared to hysteroscopy, and laparoscopy and dye test in the assessment of uterine abnormalities and tubal patency, respectively.

Early ovarian cancer: 3-D power Doppler.

Transvaginal sonography plays an important role in the assessment of the morphology of ovarian lesions. However, the accuracy of the technique is limited due to the significant number of false-positive results. Color Doppler imaging and pulsed Doppler spectral analysis enable evaluation of ovarian tumor blood flow, analysis of the distribution of blood vessels, and quantitative measurement of blood flow velocity waveforms.
