Ultrasonographic estimation of fetal gestational age by bi-parietal diameter - A cross-sectional study in an urban area of Bangladesh
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 4
Abstract
Antenatal ultrasound scanning is widely used and accepted technique to monitor fetal well-being and growth. It also helps to estimate fetal gestational age (GA) and predict expected date of delivery (EDD). Accurate estimation of GA in pregnancy is an important component of the antenatal obstetrical care. This study intends to estimate GA in second and third trimesters with the help of ultrasonographic measurements of one of the essential fetal parameter namely, the bi-parietal diameter (BPD) in the population of Bangladesh living in Dhaka city. A total of 103 healthy pregnant females were investigated with the known last menstrual period. GA is determined by measurement of fetal BPD with real time ultrasonography using Hadlock method[1-2] . There is linear relationship between GA and BPD and therefore, linear models for GA by last menstrual period (LMP) and GA by ultrasonographic measurements have been fitted by taking BPD as sole explanatory variable. Apparently, there was no violation of model assumptions during the linear model fitting process.
