The purpose of this study was to evaluate the appropriateness of transverse cerebellar diameter and abdominal circumference (TCD/AC ratio) as variables to evaluate intrauterine growth restriction of the fetus. From April 2019 to March 2021, 784 pregnant women who underwent ultrasound as a regular checkup at I hospital were retrospectively analyzed using the transverse cerebellar diameter and abdominal circumference measurements. In simple regression analysis, transverse cerebellar diameter and abdominal circumference had an effect of 97.2% and 97.5% on gestational age (p<0.001). In addition, the percentile of the TCD/AC ratio for each gestational age group was calculated through frequency analysis, and the 95th percentile of intrauterine growth restriction prediction was 14.2. As a result, it is thought that the TCD/AC ratio can be used as a useful variable to evaluate the normal growth of the fetus and predict the IUGR.

Fetal cerebellum is grow depending on the gestational age, measurement of transverse cerebellar diameter(TCD) is being used import indicator of fetal growth prediction in clinical. In this study, the subjects were normal pregnant women 20~37 week of gestation, and the volume scan was conducted on the 340 subjects. The research reports was indicated by regression curve the growth of fetal TCD in accordance with the gestational age. It got to the value of the results from a linear regression equation. Measurement fetal TCD using 3D US was statistically significant(p<0.001) and useful in the prediction of gestational age. TCD increases with gestational age can also distinguish between the normal fetal and prediction of accurate gestational age of fetal growth retardation. If the basic data of the present study, ongoing research is performed, the TCD using by 3D US are expected to be usefully applied in the correct prediction gestational age.

태아의 소뇌는 임신주수에 따라 성장하며 소뇌횡직경 길이의 측정은 태아성장 예측의 중요한 지표로 활용하고 있다. 임신주수에 따른 태아 소뇌횡직경의 성장을 회귀곡선으로 표시하였고 선형회귀방정식에서 결정계수를 얻었다. 3차원초음파를 이용한 소뇌횡직경의 측정법은 통계적으로 유의(P<0.001)하였으며, 태령을 예측함에 유용하다는 것을 알 수 있었다. 또한 성장장애가 있는 태아의 경우에도 임신주수의 예측이 가능하다. 본 연구를 기초자료로 하여 지속적인 연구가 시행된다면 정확한 임신주수 예측에 유용할 것으로 기대한다.
