| Abstract | ||
| Background: The diagnosis of fetal development problems, as well as the scheduling of elective birth, depends on an accurate gestational age (GA). In assessing gestational age in the second trimester, transcerebellar diameter (TCD) is an important biometric marker. Aim and objectives: To determine the reliability of using trans-cerebellar diameter measurements to predict gestational age in healthy, single-baby pregnancies. Subjects and methods: One hundred twenty individuals were enrolled in the prospective longitudinal comparative descriptive research at the obstetrics and gynecology departments of Al-Azhar University Hospital (Assiut) and General Sohag Hospital. The research took during the period from January 2022 to May 2023. Result: There was a highly statistically significant alteration amongst estimated gestational age by each modality (G.A-TCD, G.A-FL, G.A-BPD, and G.A-AC) and actual GA through evaluation visits and time. Accuracy within 3 days and one week significantly increased through time. There was no significant change between Actual GA and estimated gestational age by trans cerebellar diameter. However, there was a significant difference between other modalities and actual GA. Conclusion: The trans-cerebellar diameter of the fetus is a reliable predictor of the gestational age of the fetus. Its readings are highly correlated with the latest menstrual cycle's estimated gestational age. | ||
