Place and Duration of Study: FH Medical College with effect from Aug 2015- March 2017. Materials and methods: This is an observational study. Healthy pregnant ladies with a single live foetus were selected for the study. 328 cases were selected and they were examined for BPD, HC, AC, FL by a single observer on a single machine. Results: All parameters were measured in 328 pregnant females from 18 years to 35 years age for BPD, HC, AC, FL. A significant positive correlation was observed between the gestational age and all the parameters.
