Does three-dimensional power Doppler ultrasound help in discrimination between benign and malignant ovarian masses?
OBJECTIVES To determine if tumor vascularity as assessed by three-dimensional (3D) power Doppler ultrasound can be used to discriminate between benign and malignant ovarian tumors, if adding 3D power Doppler ultrasound to gray-scale imaging improves differentiation between benignity and malignancy, and if 3D power Doppler ultrasound adds more to gray-scale ultrasound than does two-dimensional (...
متن کاملThree-dimensional ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding.
BACKGROUND Ultrasonography has been extensively used in women suspected of having a gynecological malignancy. The aim of this study is to evaluate the efficacy of 3D ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding. METHODS This cross-sectional study included 78 premenopausal women with abnormal...
متن کاملThree-dimensional ultrasonography and power Doppler in ovarian cancer screening of asymptomatic peri- and postmenopausal women.
AIM To determine whether introducing three-dimensional (3D) ultrasonography with power Doppler facilities as a secondary screening test, preceded by annual transvaginal grayscale ultrasonography (TVUS) (followed by transvaginal color Doppler (TVCD) in selected cases) as a primary screening test for ovarian cancer improves the accuracy of ovarian cancer screening studies. METHODS Annual TVUS w...
متن کاملLimitations of three-dimensional power Doppler angiography in preoperative evaluation of ovarian tumors
BACKGROUND This study describes the accuracy of three-dimensional power Doppler (3D-PD) angiography as secondary method for differential diagnosis of ovarian tumors. METHOD Seventy-five women scheduled for surgical removal of adnexal masses were assessed by transvaginal ultrasound. Ovarian tumors were classified by IOTA simple rules and two three-dimensional blocks were recorded. In a second ...
متن کاملE-flow doppler indices for prediction of benign and malignant ovarian tumors.
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...
