Transvaginal color flow Doppler was used to study uterine flow and fibroid arterial supply. These studies were carried out in 101 patients with palpable uterine fibroids and 60 women attending the clinic for annual checkups. Blood flow impedance expressed as resistance index (RI), pulsatility index (PI), and blood velocity are calculated from the 5th to the(More)
OBJECTIVE To evaluate whether the number of ovarian antral follicles, ovarian volume, and ovarian stromal blood flow change with age and to prospectively analyze whether three-dimensional ultrasonographic measurements predict ovarian response and IVF outcome. DESIGN Prospective analysis. SETTING Assisted reproductive unit. PATIENT(S) Fifty-six(More)
OBJECTIVE To measure the flow velocity of the uterine and ovarian arteries through the menstrual cycle to determine there are changes. DESIGN Serial measurements throughout the menstrual cycle in women attending an infertility clinic, compared with volunteers coming for annual examinations. Transvaginal ultrasound-color flow Doppler was the investigative(More)
BACKGROUND Our study was designed to evaluate whether ovarian antral follicle number, ovarian volume, stromal area and ovarian stromal blood flow are predictive of ovarian response and IVF outcome. A total of 56 women with normal basal serum FSH concentrations who had no history of ovarian surgery, no ovarian and/or uterine pathology, were non-smokers and(More)
The aims of the study were to compare the accuracy of transvaginal ultrasonography, transvaginal color Doppler sonography, hysterosonography, and three-dimensional ultrasonography in detection of septate uterus and to evaluate the occurrence of obstetrical complications in relation to septal dimension and vascularity. Each patient underwent transvaginal(More)
Transvaginal color Doppler was used to investigate the uteroplacental circulation of 45 patients with normal intrauterine pregnancies at 4-18 weeks' gestation. The main uterine artery and the radial and spiral arteries were demonstrated, and characteristic flow velocity waveforms were obtained in more than 90% of cases. The indices of impedance to flow(More)
One thousand postmenopausal women were examined prospectively with transvaginal ultrasound. Seven hundred forty-three (74%) were asymptomatic and presented for screening. Data were analyzed to determine the accuracy of this new modality. Eighty-three women had surgery, and 29 malignant neoplasms were found. Color flow was identified in 27 of 29 malignant(More)
Approximately 50% of fetal abdominal masses originate in the urinary system and those recognizable ultrasonically include renal dysplasia, renal agenesis and obstruction of the lower excretory channels. Fetal renal anomalies may be discovered co-incidentally during the course of sonographic evaluation of uterine size-dates discrepancy, because they are(More)
The objective of this study was to investigate the usefulness of transvaginal color Doppler and three-dimensional power Doppler ultrasonography for the assessment of endometrial receptivity. A total of 89 patients undergoing in vitro fertilization procedures were evaluated for endometrial thickness and volume, endometrial morphology, and subendometrial(More)
OBJECTIVE To measure the flow velocity of the uterine, radial, spiral, and ovarian arteries during the periovulatory period in spontaneous and induced ovarian cycles with confirmed ovulation. DESIGN Daily measurements during the periovulatory period in 78 patients attending an infertility clinic because of the male factor in infertility. RESULTS Uterine(More)
