| Background: Accurately estimating a patient's gestational age (GA) is crucial for managing antenatal care and developing a treatment plan. Aim of the work: The purpose of this research was to determine the most reliable method for estimating a woman's gestational age by matching the transcerebellar diameter to the biparietal diameter to the femur length in the 3th trimester.Patient and Method: In Luxor, at Al-Hussien University Hospital & Isis Specialized Hospital, researchers analyzed data from their obstetrics and gynecology patients in a prospective observational study.. This study was done on 150 pregnant females in third trimester pregnancy, their age ranged among 18-34 years with mean value of 26.659 ± 4.062 years. The mean BMI was 24.972 ± 2.263. Regarding the parity, 8.7% were primigravida and 22.7% have history of previous abortion. Biophysical profile ranged between 8-10. Results: GA assessment by TCD has the highest accuracy of 92% while GA assessment by BPD has accuracy of 74% and GA assessment by FL has accuracy of 72%. Conclusion: In the third trimester, determining a woman's GA is best done with the trans-cerebellar diameter (TCD), then the bi-parietal diameter (BPD), and finally the femur length (FL). | ||||
