AbstractObjectivesTo assess the effect of altering image size on the absolute nuchal translucency (NT) measurement.MethodsNT was measured at three image magnifications (60%, 100% and 200%) in 120 singleton pregnancies.ResultsThe mean ± SD NT measurements were 1.52 ± 0.57 mm, 1.35 ± 0.53 mm and 1.18 ± 0.48 mm at 60%, 100% and 200% magnification, respectively (p = 0.00001).ConclusionsThe measurement of NT decreases significantly with increasing image size. Optimisation of NT as a method of screening will require agreed standardisation of image magnification. Copyright © 2003 John Wiley & Sons, Ltd.
