Abstract :

Aim: The study was conducted with the aim of evaluating the fetal biparietal diameter as a parameter for assessment of gestational age and its correlation with existing standard normograms. Material &Methods : This study consists of 100 pregnant females, between 13th to 39th weeks gestation with their age ranging from 18 –35 years, USG was done by using Gray scale real time( LOGIQ 400) machine employing a 3.5 MHz convex transducer. The biparietal diameter was measured from the outer surface of skull table of one side, to the inner margin of skull table on opposite side. Result: The mean biparietal diameter value for each gestational age was compared with the western standard showed the discrepancy of ± 3 mm and high degree of linear relationship with gestational age. Conclusion: The significance of assessment of gestational age by biparietal diameter is decreases with advancing gestational age.
