In a multicenter screening study for trisomy 21 involving ultrasonographic measurement of fetal nuchal translucency thickness (NT) at 10-14 weeks of gestation, 100,311 singleton pregnancies with a live fetus were examined. There were 46 cases of trisomy 13, and in 33 (72%) of these, the NT was above
At 10-14 weeks of gestation more than 80 per cent of fetuses affected by trisomy 21 can be detected by a screening programme based on a combination of maternal age and fetal nuchal translucency thickness (NT). The screen positive group in such a programme also identifies fetuses with sex chromosome
There is a need for a simple method of expressing nuchal translucency measurement in early pregnancy that will allow for gestational age and be useful in screening for Down's syndrome. To achieve this objective, we conducted a prospective study of 561 women with singleton pregnancies that were not a
