Transvaginal color Doppler assessment of venous flow in adnexal masses.
OBJECTIVE To analyze the usefulness of transvaginal color Doppler assessment of venous flow in the differential diagnosis of adnexal masses. MATERIAL AND METHODS Ninety-one consecutive patients (mean age: 46.6 years, range: 16-81 years) diagnosed as having an adnexal mass were evaluated by transvaginal color Doppler sonography prior to surgery. Color Doppler was used to detect and analyze the...

OBJECTIVE To assess the repeatability of measuring the pulsatility index of the uterine arteries using transvaginal color Doppler at 23 weeks of gestation. PATIENTS AND METHODS The pulsatility index was measured in 100 women with singleton pregnancies attending for routine transvaginal Doppler examination of the uterine arteries at 23 weeks. To assess the repeatability of different components...

OBJECTIVE To determine the validity of pulsatility and resistance index of transabdominal Doppler ultrasound (e-flow) in distinguishing between benign and malignant adnexal masses. METHODS A cross-sectional descriptive study was conducted on patients scheduled for elective surgery due to adnexal masses at Maharaj Nakorn Chiang Mai Hospital, Thailand, between April 2006 and March 2008. All pat...
متن کاملReference ranges for Doppler assessment of uterine artery resistance and pulsatility indices in dichorionic twin pregnancies.
OBJECTIVES To construct reference ranges of uterine artery Doppler parameters against gestation in twin pregnancies and to present charts of the pulsatility index (PI) and resistance index (RI) for clinical use. METHODS This was an observational study of the uterine circulation in 557 women with dichorionic twin pregnancies at 17-38 weeks' gestation. Uterine artery measurements were performed...
