Ultrasound evaluation of fetal gender at 12-14 weeks.
AIMS The aim of this study was to assess the feasibility and accuracy of fetal gender assignment by transabdominal ultrasound at 12-14 weeks of gestation. METHODS Fetal gender assessment was performed in 1222 singleton pregnancies. In all fetuses the crown-rump length (CRL) was measured and the genital area of the fetus was examined in the mid-sagittal plane. The result of ultrasound examinat...
متن کاملAssessment of the fetal nasal bone at 11-14 weeks of gestation by three-dimensional ultrasound.
OBJECTIVE To evaluate the benefit of three-dimensional (3D) ultrasound in the examination of the fetal nasal bone at 11-14 weeks of gestation. METHOD We examined the fetal nasal bone in 120 stored volumes acquired transabdominally with a 3D scanner from singleton pregnancies at 11-14 weeks of gestation. The volume acquisition had been performed following conventional ultrasound examination th...
متن کاملIncreased fetal nuchal translucency at 11-14 weeks.
Nuchal translucency (NT) is the sonographic appearance of a subcutaneous collection of fluid behind the fetal neck. The measurement of fetal NT thickness at the 11-14-week scan has been combined with maternal age to provide an effective method of screening for trisomy 21; for an invasive testing rate of 5%, about 75% of trisomic pregnancies can be identified. When maternal serum free-beta human...
متن کاملDo early pregnancy ultrasound measurements correlate with fetal nuchal translucency at 11-14 weeks?
OBJECTIVE To assess whether extremes in nuchal translucency (NT) thickness measurements at 11-14 weeks of gestation are preceded by departures from normal in early ultrasound biometry or embryonic heart rate in euploid fetuses. METHODS This was a retrospective analysis of data from women with singleton pregnancies examined in early pregnancy between June 2002 and January 2003, who subsequentl...
متن کاملThe sonographic identification of fetal gender from 11 to 14 weeks of gestation.
OBJECTIVE To determine the feasibility of correctly identifying fetal gender from 11 to 14 weeks' gestation. METHODS A prospective cross-sectional study in a university Department of Obstetrics and Gynaecology, London. A total of 524 women from an unselected population underwent a detailed assessment of fetal anatomy at 11-14 weeks of gestation (confirmed by crown-rump length) by means of tra...
