Abstract:
Fetal biparietal diameter measured with linear- array, real-time ultrasound scanner in 114 uncomplicated gravid patients from 30 to 42 weeks gestation. The date were analyzed by means of the of least-squares linear regression. The results of this analysis generated the following equation: y= 1.59x+ 30.54 (r= 0.08), (y= biparietal diameter, x= gestational age). The growth rate of the biparietal diameter has also been calculated (1.59mm/wk). With the use of this date, the error in estimation of gestational age given biparietal diameter in the interval 30 to 42 weeks gestation is +/- 14 days. Biparietal measurements provide the first reproductive determination of length of the fetus to be mesured by ultrasound throughout pregnancy.
