Retrospective review of diagnostic performance of intracranial translucency in detection of open spina bifida at the 11–13‐week scan

Abstract

There was moderate interobserver agreement for visualization of IT on images obtained for nuchal translucency measurement at 11-13 weeks. When IT was confidently seen, open spina bifida could be excluded. However, non-visibility of IT correctly diagnosed only 50% of fetuses with open spina bifida.
