2. 1. Fetal Anomalies : Surveillance and Diagnostic Accuracy of Ultrasound and Magnetic Resonance Imaging

   Author : Hashem Amini; Ove Axelsson; Johan Wikström; Pelle Lindqvist; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pregnancy termination; fetal anomalies; antenatal diagnosis; ultrasound; second trimester; fetal MRI; CNS anomalies; pregnancy management; non-CNS anomalies; fetal autopsy; birth defects registry; ascertainment; spina bifida; cleft lip palate; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and gynaecology; Obstetrik och gynekologi; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Abstract : The aims were to investigate the accuracy of ultrasound in diagnosis of structural fetal anomalies with special focus on false positive findings (I), to evaluate the additional value of second trimester fetal MRI on pregnancy management (II-III) and to estimate the ascertainment in the Swedish Birth Defects Registry and incidence of spina bifida and cleft lip/palate (IV). Retrospectively, 328 fetal autopsies were identified where pregnancies were terminated due to ultrasonographically diagnosed fetal anomalies. READ MORE

4. 2. Ultrasound screening for fetal anomalies

   Author : Annamari Nikkilä; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexuality; Obstetrik; andrology; congenital malformations; ultrasound; gynekologi; andrologi; reproduktion; sexualitet; reproduction; gynaecology; Obstetrics; fetal diagnosis;

   Abstract : We studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. READ MORE

5. 3. Fractional moving blood volume in fetal organs estimated using power Doppler ultrasound

   Author : Edgar Hernandez-Andrade; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; andrology; gynaecology; Obstetrics; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; fetal adrenal gland; fetal lung; radionuclear microspheres; fetal lamb; perfusion; fetus; Power Doppler ultrasound; fractional moving blood volume;

   Abstract : Power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. The aim of the present study was to develop a standardized method for quantification of the PDU signals recorded from a specific region of interest (ROI) within fetal organs. READ MORE

6. 4. Ultrasound prediction of large fetuses. Epidemiological and clinical investigations

   Author : Gun Lindell; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Two-dimensional ultrasound; three-dimensional ultrasound; fetus; intrauterine growth; maternal characteristic; large-for-gestational age; antenatal calculation; Bayesian theorem; fetal weight; estimation; post-term fetus; fetal macrosomia;

   Abstract : The proportions of newborns with a birth weight (BW) >4,000 g and of macrosomic newborns (BW >4,500 g) have increased during the last two decades, parallel with an increasing maternal pre-pregnancy body mass index (BMI) and age at the time for pregnancy. Delivery of a large fetus, especially >4,500 g might cause perinatal complications for both the mother and her child. READ MORE

7. 5. Fetal surveillance and outcome in postterm pregnancy

   Author : Margareta Kitlinski; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet; reproduction; andrology; gynaecology; Obstetrics; Ultrasound.; Umbilical cord artery; Prolonged; Postterm; pH; Mortality; Morbidity; Gender; Fetal surveillance; Brain-sparing; Doppler; Blood gases; Acid-base;

   Abstract : To minimize the risk of short-term and long-term morbidity and mortality among children born postterm, studies were performed to evaluate the fetal surveillance program. (1) Male-fetus pregnancies were at an increased risk... READ MORE
