ABSTRACT:
The purpose of the study was to analyze the diagnostic accuracy of transcerebellar diameter and BPD in determining the gestational age when the LMP is known in third trimester of pregnancy Methodology: The current study was conducted in Radiology Department of Lahore General Hospital from time period of September 2018 to October 2019.The sample size selected was 150 women with singleton pregnancy in third trimester. Ultrasound was performed on 150 women and trans cerebellar diameter, biparietal diameter (BPD) and also FL (femur length) were measured. Results: The results of the study showed that all the women (150) included with known LMP have no significant difference in gestational age calculated by trans cerebellar diameter and BPD by ultrasound measurements and the gestational age calculated by the LMP. The mean gestational age calculated was 35.20 ±3.42 weeks (26-40 weeks range). Therefore, TCD is a reliable parameter of gestational age predicting. It is very helpful in special cases like IUGR for timely intervention. Conclusion: Trans cerebellar diameter is considered accurate along with biparietal diameter and femur length in predicting the gestational age in pregnancy in last trimester. Key Words: Singleton pregnancy, Transcerebellar diameter, femur length, gestational age
