ABSTRACT

Introduction: Prediction of gestational age (GA) based on sonographic fetal parameters is essential in modern obstetrics and continues to remain an important component in the management of pregnancies. A variety of sonographic fetal parameters have been shown to correlate well with gestational age. Transcerebellar diameter (TCD) is one such fetal parameter that has remained consistently superior in predicting gestational age.

Aims and objective: Compare the efficacy of transverse diameter of fetal cerebellum and length of fetal femur in predicting gestational age.

Materials and Methods: About 100 pregnant women seeking antenatal care and undergoing routine ultrasound examination were selected for the study. Fetal transverse cerebellar diameter and femoral length measurements were recorded along with gestational age. Ultrasonographic fetal maturity was determined using all biometric parameters and efficacy of transcerebellar diameter and femoral length was compared.

Results: Patients were divided into five groups as per their gestational age.  In each group mean and standard deviation for values of TCD and FL was calculated and their statistical significance is found out.

Discussion: Our study found that both TCD and FL go on increasing as gestational age increases. Results of this study are compared with other workers.

Conclusion: Our study shows that TCD is equivalent to FL as a biometric parameter for evaluating gestational age in first & second trimester but it less effective than FL in the third trimester.

Key words: Transcerebellar diameter, gestational age, Femoral length, Ultrasonography.
