Abstract
The purpose of this study was to present the reference value of the intracranial translucency(IT) of the fetus using the mid sagittal plane of the post brain in the early pregnancy ultrasound screening test and to find the clinical significance. From August 2018 to February 2020, the IT of 1529 singleton fetus whose crown lump length were 40.6 mm to 78.3 mm in length among the mothers undergoing regular checkups at Hospital I were measured and analyzed retrospectively. As the crown lump length increased, the IT showed a 54.3% explanatory power and tended to increase(p<0.001). In addition, through frequency analysis, the standard value for the percentile of the IT by gestational weeks was calculated. As a result, it was possible to establish a standard value for Koreans with an IT, and it will be usefully applied as an auxiliary screening test for spina bifida in the evaluation of fetal post brain in early pregnancy.
