Does transvaginal color Doppler sonography differentiate between developing and involuting ectopic pregnancies?
The objective of this study was to assess the addition of transvaginal color Doppler imaging to transvaginal ultrasonography and beta-human chorionic gonadotropin values to differentiate between developin and involuting ectopic pregnancies. Forty surgically confirmed ectopic pregnancies were classified into developing or involuting according to histopathologic findings. Results were compared retrospectively with the plasma beta-human chorionic gonadotropin values as well as the resistive index and pulsatility index obtained in corpora lutea and peritrophoblastic flow in serial examinations. Student's t-test was used for comparison of means. Logistic regression analysis was applied to predic…
Diagnosis of Endometrial Carcinoma: Predictive Value of Transvaginal Color Doppler
The objective of this study was to determine whether transvaginal ultrasound plus color Doppler flow improve the ability to diagnose endometrial carcinoma and allow better discrimination between benign and malignant endometrial lesions. One hundred thirty women with abnormal uterine bleeding were evaluated with transvaginal color Doppler before fractional dilatation and curettage (D&C). The endometrial line thickness and endometrial characteristics were evaluated by endosonography. The resistive and pulsatile indices of the uterine arteries and of the endometrium were evaluated with transvaginal color Doppler. Following D&C and tissue diagnosis, women were divided into two groups, 62 with a…
