Objective: To establish the usefulness of fetal cerebellar transverse diametermeasurement for the prediction of gestational age. Design: Prospective, longitudinal,cohort study. Institution: Hospital Central "Dr. Urquinaona", Maracaibo, Venezuela.Participants: Women with low-risk singleton pregnancies, between 14 and 40weeks of gestation. Methods: Biparietal diameter, abdominal circumference, femurlength, and transverse diameter of the fetal cerebellum were measured during theduration of pregnancy. Main outcome measures: Prediction of gestational age bymeasurement of the transverse diameter of the cerebellum. Results: Data from 215pregnant women were selected. A total of 3,858 total evaluations were performed,with the lowest number of evaluations 131 at 18 weeks and the highest number 157at 28 weeks. The transverse diameter of the cerebellum presented strong, positive,and significant correlations with gestational age by date of last menstrual periodand ultrasound measurements (p < 0.001). The model of gestational age predictedby the transverse diameter of the cerebellum reached a value of the coefficient ofdetermination of 0.908. The correlation between gestational age by date of lastmenstrual period and that predicted by the model reached a value of r = 0.953 (p <0.001). Conclusion: Measurement of the transverse diameter of the cerebellum is auseful parameter for predicting gestational age in healthy pregnant women.
