The value of screening for major fetal abnormalities during the nuchal translucency examination

The nuchal translucency (NT) scan provides an opportunity to examine fetal anatomy. Current opinion on the advantages and limitations of assessing fetal anatomy at this early gestation is divided. Two case studies from our centre will be presented where assessing fetal anatomy was of great benefit - one in finding abnormalities, the other in excluding them. These cases along with review of the literature support the view that a limited fetal anatomy scan should be performed as part of the NT examination.
