Undetected cases after implementation of first‐trimester anomaly scan in low‐risk population: insights from the <scp>IMITAS</scp> study
Nearly 1% of pregnancies with a normal FTAS result were diagnosed with a structural anomaly in the second trimester, including 23 major anomalies amenable to detection in the first trimester (accounting for 0.02% of scans with a normal result). Missing mandatory planes and acquisition of suboptimal planes were the main reasons for the overlooked FTMA diagnoses. Improvements are expected with increasing sonographer experience, additional training and possible expansion of the protocol. © 2025 The Author(s).
