Abstract

With the advent of nuchal translucency as a screening test for trisomy 21, increasing numbers of women are having an ultrasound scan between 11 and 14 weeks. The RCOG Working Party (July 2000) recommendations for ultrasound in pregnancy do not mention a first trimester scan for nuchal translucency or fetal anatomy. However, this scan is not just an opportunity to perform nuchal translucency; many structural abnormalities can also be seen at this stage.
