Abstract Objective: To evaluate the feasibility of nuchal translucency(NT) measurement through standard midsagittal section acquired by three-dimensional(3D) ultrasound. Methods: 198 cases of 11+2～14+2 weeks of gestational age fetus underwent 2D and 3D ultrasound, NT was measured, comparative measurements between 2D and 3D ultrasound were performed to see whether there was significant difference. Results: The statistical assessment for all the 198 fetuses showed that the difference of NT values measured by 2D and 3D ultrasound was not significant(t=0.488, P=0.626＞0.05), positive correlations were found between NT value and gestational age for both methods(r=0.536, P<0.05; r=0.543, P<0.05). Conclusion: Reconstruction and 3D extended imaging could obtain standard midsagittal section essential for NT measurement, so it is feasible to measure NT by 3D ultrasound, and its clinical value should be confirmed.
