Fetal Transverse Cerebellar Diameter Measurement for Prediction of Gestational Age in Pregnant Sudanese Ladies

Abstract

This study was carried out to evaluate whether Transverse Cerebellar Diameter (TCD) in singleton gestations can serve as a reliable predictor of gestational age (GA) in fetuses in the second and third trimester of pregnancy. A prospective study was carried out with 50 pregnant ladies, GA ranging from 15to37 weeks (estimation of mean GA was 26.8 ± 6.8 weeks), with a single fetus.TCD measurement by ultrasound was used for each fetus. Correlations between fetal TCD and GA were determined for the whole sample. Mean TCD was 28.6 ± 7.5 mm in 15-37 weeks of gestation. Regression analysis indicates a significant relationship between TCD and GA; correlation coefficient (r) = 0.94 and p< 0.001. Fetal TCD by ultrasound could be a predictive biometric parameter of GA in the last two trimesters of a pregnancy. Keywords-Fetal Transverse Cerebellar Diameter (TCD); Gestational age (GA); Ultrasound
