- Abstract
To assess the effect of altering image size on the absolute nuchal translucency (NT) measurement. NT was measured at three image magnifications (60%, 100% and 200%) in 120 singleton pregnancies. The 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). The measurement of NT decreases significantly with increasing image size. Optimisation of NT as a method of screening will require agreed standardisation of image magnification.
