Backround One of the most useful US markers for fetal aneuploidy and other structural anomalies is measurement of nuchal translucency (NT). Using conventional 2D ultrasound, irrespective of high quality of current devices, brings problems connected with fetal intauterine possition. Unfavourable position increases intra‐and interobserver variability of measurement or can even disables the evaluation. Method In this study the fetal textbook ‘standard’ position for measurement of NT using konventional 2D and 3D was performed in 105 cases in 11th − 14th week of pregnancy, 3x in each case. Two aspects were evaluated: succes of achieving standard position and variability of individual measurement. Results The nuchal translucency with 2D scanner was measurable in 63% of cases. With 3D vaginal scanner, using computed 2D multiplanar analysis the correct and standart plane was achieved in 97% the cases. The exactness of 3D measurement is significantly higher. Conclusions The problems with fetal position seems to be solved using 3D computer sonography with its electronic tools as multiplanar 2D and possibility of electronic rotational display of embryo. 3D decreased the interobserver and intraobserver error to minimum. The 3D multiplanar analysis was found to be superior.
