Intraobserver and interobserver variability of ovarian volume, gray-scale and color flow indices obtained using transvaginal three-dimensional power Doppler ultrasonography.

OBJECTIVE To assess intraobserver and interobserver variability in ovarian volume and gray-scale and color flow index measurements using transvaginal, three-dimensional, power Doppler ultrasonography. METHODS Eleven women (22 ovaries) were examined on day 8 of controlled ovarian hyperstimulation therapy, which was part of their in vitro fertilization treatment protocol. The patients were exam...

Intraobserver and interobserver reproducibility of three-dimensional gray-scale and power Doppler ultrasound examinations of the cervix in pregnant women.

OBJECTIVES To determine intraobserver and interobserver reproducibility of three-dimensional (3D) gray-scale and power Doppler ultrasound examinations of the cervix in pregnant women. METHODS Thirty-two pregnant women underwent transvaginal 3D gray-scale and power Doppler ultrasound examination of the cervix by two examiners. Each observer acquired two volumes, and they each analyzed their vo...

Cervical Volume and Flow Indices during Pregnancy by Transvaginal 3-dimensional Ultrasonography and Doppler Angiography

Recent studies have shown that transvaginal ultrasound provides a more reliable and objective evaluation of the uterine cervix, demonstrating that the shorter the length of the cervix the higher the risk of preterm delivery. Measuring cervical volume could even be a better reflection of cervical morphology. Three-dimensional (3D) imaging combined with power Doppler, theoretically provides the p...

Testicular Arteriovenous Malformation: Gray-Scale and Color Doppler Ultrasonography Features

Intratesticular arteriovenous malformations (AVMs) are extremely rare benign incidental lesions of the testis. Ultrasonography (US) generally reveals a hypoechoic solid mass within the testicular parenchyma. We describe a patient with intratesticular AVM which was found incidentally during workup for infertility. The gray-scale and Doppler US appearance of an intratesticular AVM and the differe...
