Do you need anomaly scan after nuchal translucency scan?

A nuchal translucency scan is performed earlier in pregnancy and measures the fluid space at the back of the baby's neck alongside other early pregnancy observations. It contributes to screening and dating information. An anomaly scan is performed later, when the baby's organs and body structures can be assessed in greater detail.

A reassuring nuchal translucency result does not replace the later structural assessment. Neither scan examines every possible condition, and an ultrasound finding may lead to additional imaging or specialist review.

Keep the anomaly-scan appointment offered by your maternity team, even if the earlier scan was reassuring. Ask what the scan will assess, whether you need a full bladder or other preparation, and how results will be explained. Tell the sonographer or clinician about previous scan findings and any concerns about your pregnancy.

If the view is limited by fetal position or another practical issue, the team may arrange another appointment. This does not by itself mean that a problem has been found.

Contact your maternity team promptly for vaginal bleeding, leaking fluid, severe abdominal pain, fever, or a sudden change in your wellbeing. Later in pregnancy, report reduced fetal movement according to the instructions you were given. Seek emergency care for heavy bleeding, collapse, or severe pain rather than waiting for a scheduled scan.

Ask: What did my nuchal translucency scan assess? What will the anomaly scan examine? When should it happen? Could I need further imaging? How and when will I receive the findings?
