Background: To find out correlation between biparietal diameter and gestational age
Methods: This was a cross sectional study of uncomplicated pregnant women who presented for routine obstetric ultrasound at S M S medical college & hospital.
Informed consent was obtained from the patients before inclusion in the study. Only singleton pregnancies were included. Exclusion criteria included pregnant women who had concomitant disease that could possibly affect fetal growth (e.g. diabetes mellitus, asthma, hypertension, renal disease, thyroid disease), complicated pregnancy (e.g. bleeding, preeclampsia), foetal abnormality detected during the examination, women with a history of obstetric complications, intrauterine growth retardation and macrosomia
Results: The cases were in the age group of 18 to 37 yrs. Maximum number of cases are in middle age group and minimal in elderly age group. Mean BPD at 41 weeks of gestational age was 89.00 mm and 40 weeks of gestational age was 88.00±3.42 mm.
Conclusion: It can be concluded from the study that there is good correlation of BPD measurement by ultrasonography and gestational age. It is a reliable tool especially in those women where LMP is not known or doubtful, for assessing gestational age.
