- Abstract
<bold>Purpose: </bold>The aim of this study was to determine the correlation between fetal transverse cerebellar diameter (TCD) and gestational age of male and female fetus in women under low-risk prenatal care between the 13th and 40th week of gestation. <bold>Methods: </bold>A cross-sectional study was carried out with 184 pregnant women, at the age of 18 years or more, gestational age ranging from 13 to 40 weeks, with a single fetus. A single TCD measurement by ultrasound was used for each fetus. Correlations between fetal TCD and gestational age were determined for the whole sample and each gender separately. <bold>Results: </bold>We identified 102 males and 82 female fetuses. A linear correlation was observed between fetal TCD and gestational age for the whole sample (r = 96.9%; p < 0.001). A significant linear correlation was also observed for both males (r = 97.0%; p < 0.001) and females (r = 96.9%; p < 0.001). Comparing the regression lines between genders, no significant difference was observed. <bold>Conclusions: </bold>The data of this study suggest TCD fetal ultrasound as a predictive biometric parameter of gestational age independently of fetal gender in the last two trimesters of a pregnancy.
