Introduction: The gestational age estimation is an essential part of the care and management of pregnant women. A number of methods have been used for fetal dating and ultrasonography have become as an integral part of Obstetrics. Objective of this study is to determine whether Ultrasonography (USG) based Expected date of delivery (EDD) is better or Last menstrual period (LMP) based EDD.
Materials and Method: This study was done on randomly selected 50 pregnant women. Cases were selected from those attending antenatal clinic, labour room, Indoor and outdoor of the Department of Obstetrics and Gynaecology, at medical college and hospital Kolkata. The parameters like Crown-Rump Length (CRL), Bi-parietal Diameter (BPD), and Femur Length (FL) were used to determine Gestational Age (GA) during 1st, 2nd and 3rd trimester with help of USG.
Result: The CRL was better parameter to determine GA in first trimester and BPD and FL was better parameters to determine GA in second and third trimester for gestational age estimation. The CRL, BPD and FL parameters together give the best assessment of GA in Uterus.
Conclusion: USG is a better diagnostic tool for estimation of EDD than the LMP method.
