What is the normal BPD at 20 weeks?
Results: The mean biparietal diameter value was 29.4mm at 14 weeks, 49.4mm at 20 weeks, 78.4mm at 30 weeks, 91.5 at 37 weeks and 95.6mm at 40 weeks. There was a positive relationship between gestational age and biparietal diameter with correlation coefficient of R2 = 0.9996 (P < 0.001), and with fetal weight.
What should BPD be at 20 weeks in CM?
Observation and Results: In this study, fetal mean BPD showed a linear increase from 13 to 36 weeks. Statistically significant correlation was found between GA and BPD (r = 0.38). Mean BPD showed an increase of 2.38 cm in 13-20 weeks, 2.18 cm between 20 and 27 weeks and only 1.72 cm from 27 to 34 weeks.
