This document is a reply to a correspondence regarding a publication in the journal Ultrasound in Obstetrics & Gynecology. The authors agree with the caution expressed by Drs Jiang and Li about adding more scans to the prenatal screening program for congenital anomalies. While their study does not advocate for incorporating nuchal translucency measurements in the early first trimester, they emphasize that an increased nuchal translucency is a marker for congenital anomalies and should not be ignored. The authors recommend prompt referral to a fetal medicine unit for further counseling and diagnostic testing, and suggest that the first- and second-trimester anomaly scans should always be performed in a fetal medicine unit.
