ABSTRACT: Background: Prediction of gestational age (GA) based on sonographic fetal parameters is perhaps the cornerstone of modern obstetrics and continues to be an important component in the management of pregnancies with fetuses with growth disturbances. Trans cerebellar diameter is one of the parameters that can be used to estimate gestational age. Objectives: The study’s objectives were to compare the accuracy of cerebellar measurement (transverse and median longitudinal (MLM) in determining GA between the 14th and 40th weeks to that of other fetal biometric parameters. Material and Methods: This was a prospective cross-sectional study conducted in Khartoum, Sudan, from August 2015 to January 2016. 385 healthy pregnant women with normal fetal ages ranging from 15 to 45 years were examined by ultrasound. The transcerebellar diameter (TCD), biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) were measured using ultrasound to determine GA, and the data were collected and analyzed. Results: In normal pregnancy, TCD increases with advancing age, with a linear relationship between TCD and gestational age. The present study showed that the mean ± SD GA was (26.5 ± 6.8) weeks, and the mean ± SD TCD was 28.05 ± 7.6. Also, the correlation between the TCD and fetal age was 0.720, as well as between the TCD and other parameters (BPD, MLM, and HC), which were 0.819, 0792, and 0.763, respectively. Conclusion: According to the findings of this study, TCD and MLM are simple to identify and measure; they are the most accurate single parameters for estimating GA compared to other biometric indices, and they can be easily incorporated into models for estimating GA. These charts will also assist radiologists and clinicians in predicting delivery dates, assessing fetal growth, and identifying intrauterine fetal insufficiency in the Sudanese population.
