An early structural scan is a first trimester obstetric ultrasound performed around 12-16 weeks gestation. It can have some similarity to the 11-13 week antenatal ultrasound and assess limited fetal anatomy. However, a formal evaluation of nuchal translucency is not part of this ultrasound assessment.
