In recent years, investigations of the venous vascular system have become increasingly important in the assessment of fetal myocardial function. The aim of the present Doppler ultrasound study was to establish both new reference ranges for blood flow velocity during the different phases of the cardiac cycle (S, SD, D, a) and various calculated indices(More)
Uterine and ovarian size were measured in 765 pre- and postmenopausal women by transvaginal ultrasound. Of these, 263 (premenopausal, n = 155; postmenopausal, n = 108) were found to have neither uterine nor ovarian pathological findings. According to parity, premenopausal women were separated into three groups: nullipara, primipara and multipara.(More)
At the Department of Gynaecology and Obstetrics of the University of Mainz, the foetal weights were estimated in 196 foetuses between 24 and 42 weeks of gestation. All estimates were based on sonographic determination 0-6 days prior to delivery. In a prospective study the equations of Hansmann, Schillinger et al., Campbell and Wilkin, Warsof et al., Shepard(More)
OBJECTIVE The problem of an accurate sonographic assessment of ovarian tumor status has not yet been solved. To what extent can the preoperative assessment of adnexal tumors be improved on the basis of a maximum number of sonographic tumor parameters included in the newly developed sonomorphologic Mainz Score? MATERIALS AND METHODS In a prospective study(More)
PURPOSE First-trimester screening at 11 - 14 weeks has been proven to be very useful in the early detection of chromosomal defects. The aim of this project was to develop a CE-certified new risk calculation program (PRC = Prenatal Risk Calculation) using a nationwide database. MATERIALS AND METHODS The database underlying the new risk calculation(More)
Between July 2000 and December 2003, a total number of 3,472 fetuses was evaluated by two-dimensional (2D) and three-dimensional (3D) ultrasonography. All examinations were carried out as part of a detailed level III ultrasound examination for fetal anomalies. The gestational age was between 11 and 35 weeks. A 3D endovaginal probe (5 - 7 MHz) was used for(More)
AIM Age-related and uniformly defined standard graphs were obtained for the fetal parameters BPD, OFD, HC, ATD, ASD, AC, Fe, Ti, Fi, Hu, Ra and Ul. METHODS Data of 2032 healthy pregnant women of sonographically confirmed gestational age were used in a prospective cross-sectional study to establish reference charts for the fetal head and abdomen and the(More)
OBJECTIVES It was the aim of the present study to calculate new Doppler reference ranges for blood flow velocities (Vmax, Vmean, Vmin) and resistance indices (PI, RI) for the fetal descending aorta by automatic waveform analysis. DESIGN Cross-sectional prospective study. SUBJECTS Nine hundred and twenty-six low-risk pregnancies at 18-41 weeks'(More)
