Screening for trisomies in dichorionic twins by measurement of fetal nuchal translucency thickness according to the mixture model
1 Jan 2011
Abstract excerpt
OBJECTIVE: To examine the distribution of fetal nuchal translucency (NT) thickness in dichorionic twins and investigate the effect of the correlation between NT measurements in each twin pair on the performance of screening for trisomies. METHODS: The distribution of fetal NT for crown-rump length (CRL) was examined in 5646 dichorionic twin pregnancies, including 103 with fetal trisomies 21, 18 or 13. The...
