Question
When should I schedule my NT scan during the 11th week of pregnancy?
Answer
The optimal time for an NT scan is between 11 to 14 weeks of pregnancy, as the accuracy decreases after 14 weeks. The NT scan primarily measures the thickness of fluid under the baby’s neck using an ultrasound, with a normal value being less than 3 millimeters. If the measured value is less than 3 millimeters, further investigation, such as amniocentesis, may be required.
