There are 2 very important scans that should be done during your pregnancy:
Nuchal Translucency (NT) ultrasound scan
The NT scan forms part of a screening programme for Down’s Syndrome. The thickness of the fluid behind the baby’s neck is measured. The measurment is taken between 11 and 14 weeks. Down’s babies usually have thicker nuchal translucencies. The NT measurement, combined with blood tests and the mom’s age, can calculate a risk for Down’s Syndrome.
Fetal Anomaly ultrasound scan (Anatomy scan)
The fetal anomaly scan is performed between 18 and 23 weeks. The main objective of this scan is to assess all the structural anatomy of the baby.
