AbstractIntroduction: The estimates of age based on measurements of Head Circumference can be used as an alternative in pregnancy dating. These additional measurements taken provide a more ‘universal view’ of the foetal development than can be afforded by any single measurement. In the present study Bi-parietal diameter [BPD] & Head Circumference [HC] were measured to study the correlation and significance of this parameter with LNMP in estimating the foetal gestational age [FGA].
Material and Methods: In the Present study, a total of 100 antenatal women attending Out-Patient Department of Obstetrics and Gynaecology at Government Maternity Hospital, Sultan Bazaar, during the period of January 2016 to August 2016 i.e. for eight months were included in the study, undergone ultrasonography of multiple bone parameters including BPD & HC. Result: BPD and LNMP and HC and LNMP value in Total estimating the FGA with correlation coefficient r value of 0.967 and 0.965 respectively, correlation was significant at < 0.01 level (p value 0.000) and < 0.01 level (p value 0.000) respectively. In second Trimester r value of 0.895 and 0.885 respectively, and correlation was significant at the 0.01 levels (p value 0.000) and < 0.01 level (p value 0.000). In 3rd Trimester r value of 0.771 and correlation is significant at < 0.01 level (p value 0.000) and 0.740 and correlation was significant at <0.01 level (p value 0.000). When the correlation coefficient r-values were compared, BPD (0.967), had highest r-value followed by HC (0.965), in the study population, as well as when compared trimester wise.
