   Abstract : BackgroundObstetric ultrasound has become an indispensable part of maternity care in high-income countries, where it is universally used for screening, diagnostic and surveillance purposes. In low-income countries, insufficient numbers of trained health professionals’ is commonly a barrier to obstetric ultrasound use. READ MORE

4. 2. Three-dimensional ultrasound studies of normal and abnormal ovaries

   Author : Ligita Jokubkiene; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovary; ovarian follicle; ovarian neoplasms; ultrasonography; three-dimensional imaging; Doppler ultrasound imaging; vascular morphology;

   Abstract : The aims of this work were: 1) to estimate the number of follicles, ovarian volume and power Doppler vascular indices and their changes with age using three-dimensional (3D) transvaginal grey-scale and power Doppler ultrasound in asymptomatic women of fertile age either with natural menstrual cycles or using combined oral contraceptives, and 2) to determine whether tumour vascularity, assessed by 3D power Doppler ultrasound, can help discriminate between benign and malignant ovarian tumours. A group of 303 gynaecologically asymptomatic women, aged 20–39 years with normal menstrual cycles (NMC) and another group of 213 women aged 20–39 years using combined oral contraceptives (COC) were examined using two-dimensional (2D) and 3D transvaginal ultrasound once between cycle day 4 and 8.

6. 4. Prenatal diagnosis in routine antenatal care : a randomised controlled trial

   Author : Sissel Saltvedt; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Ultrasound; fetal ultrasonography; Down s syndrome; chromosomal disorder; nuchal translucency; genetic screening; prenatal diagnosis; abnormalities; gestational age; in vitro fertilization; fetometry; dating formulas; false positive reactions; anxiety;

   Abstract : Nuchal translucency (NT) measurement combined with maternal age has been shown to identify women at an increased risk of carrying a fetus with Down's syndrome (DS) more accurately than does maternal age alone. The aim of this study was to evaluate more widely the effects of two different strategies for prenatal diagnosis. READ MORE

7. 5. Ultrasound Studies of Caesarean Hysterotomy Scars

   Author : Olga Vikhareva; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The aim of the work presented in this thesis was to investigate how transvaginal ultrasound examination of non-pregnant women could be used to visualize and assess caesarean hysterotomy scars, and to evaluate the risk of uterine rupture in subsequent pregnancies. The diagnostic value of transvaginal ultrasound for correct evaluation of caesarean hysterotomy scars was determined, and the prevalence of defective scars was estimated. READ MORE
