Sonographic size of uterus and ovaries in pre- and postmenopausal women
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. Postmenopausal women were separated into two groups according to years since menopause: 5 years since menopause. In the premenopausal group, a parity-related enlargement in uterine size was observed between nulliparous and parous women. After the menopause, a significant reduction in uterine size and in the corpus-cervix ratio was observed. The red…
Application of transvaginal and abdominal three-dimensional ultrasound for the detection or exclusion of malformations of the fetal face
In a total of 618 pregnant women between 9 and 37 weeks' gestation, the fetal face was evaluated by two-dimensional and three-dimensional ultrasound imaging as part of a level III screening evaluation for fetal anomalies. A three-dimensional endovaginal probe (5 MHz) was used for examinations at between 9 and 15 weeks, and an abdominal three-dimensional probe (3.5 MHz) was used after 15 weeks. Three different three-dimensional image display modes were employed: (1) the orthogonal display; (2) the surface display; and (3) the transparent display. When we studied the three-dimensional orthogonal displays in 125 cases evaluated by abdominal ultrasound, we found that the facial profile shown in…
Value of the electronic scalpel (cut mode) in the evaluation of the fetal face
Objectives To evaluate the improvement of image quality and diagnostic value of fetal face examinations using the electric scalpel. Methods A total of 232 cases were examined. The fetuses were separated into two groups: Group A, including normal fetuses (n = 152) and Group B, fetuses with facial pathology (n = 80). The fetuses were divided into eight subgroups according to gestational age (9–12 weeks, 13–16 weeks, 17–20 weeks, 21–24 weeks, 25–28 weeks, 29–32 weeks, 33–36 weeks and 37–40 weeks). Results The number of cutting steps for the improvement of image quality ranged from 1 to 9 (mean value 3) in the group of normal fetuses and from 1 to 10 (mean value 3) in the group of fetuses with …
F75Determining fetal lung volume using three-dimensional-ultrasonography
Background The aim of the study was to establish fetal lung, thoracic and heart volume nomograms using 3D-ultrasonography. Method For this purpose 115 fetuses were examined (between 18 and 33 weeks of gestation) using Voluson 530D (Kretztechnik, Austria) ultrasound device and 5 MHZ three-dimensional annular volume transducer. Lung volumes of 15 fetuses suffering from skeletal dysplasia, renal agenesis or hydrothorax and secondary pulmonary hypoplasia were compared with previously established nomograms. Results Lung volumes in the pathologic group of fetuses compared to the nomograms were below the 5% for gestational age. Conclusion The encouraging first results suggest that this method coul…
