Ultrasound (US) examination at 11–14 weeks of gestation aims to confirm the gestational age, determinate chorionicity for multiple pregnancies, measure the nuchal translucency (NT) thickness to assess the risk of aneuploidy, and to visualize the basic anatomical structures of the fetus (Guidelines ...

Case-3: ectopia cordis in 8 weeks fetus- ultrasound video There is also a bilateral jugular lymphatic sac observed in this fetus. The fetal heart lies entirely outside the confines of the thoracic cage.The above 3 B-mode ultrasound images show the fetal heart lying partially outside the ...
A patient who was delivered of an infant affected with diastrophic dwarfism syndrome was diagnosed at 16 weeks' gestation to have a fetus affected with this problem. Two other patients whose pregnancies were at risk for skeletal dysplasias were correctly diagnosed to be normal.John...
Ultrasound, for the purpose of gender determination, is optimal beginning at 17 weeks. We often times can determine gender after 15 weeks but we "guarantee" it after 17 weeks. Our technicians are highly skilled at using the ultrasound technology to our best advantage in determining gender and,...

Methods Fetal biometric measurements were obtained at entry to antenatal care (11-22 weeks' gestation) and thereafter at 4-week intervals front pregnant women enrolled in a longitudinal ultrasound study in Kinshasa,, Democratic Republic of Congo. The study population comprised 144 singleton gestations ...
The evaluation of uterine anatomy at term is challenging. The grown fetus usually obstructs the view of the posterior elements of the uterus. The evaluation of adnexa and ovaries is also often not possible as the structures are high up in the abdominal cavity and out of the scanning depth. ...
It has been classified into early-onset (detected before 32 weeks' gestation) and late-onset (detected after 32 weeks' gestation) types5, 6. Fetuses with suspected FGR will not necessarily be SGA at delivery, and a fetus may fail to achieve its growth potential despite not being SGA at...
In fact, examination of time necessary for the female fetus to reach male size showed that this increased from one day at 8–12 weeks to 6 or 7 days at term15. Several hypotheses have been postulated to explain this gender-specific growth pattern. Thomson et al. suggested that sex hormone...
