Abstract:
Fetal femur length and biparietal diameter measured with a linear array, realtime ultrasound scanner in 114 normal gravid patients of 31 to 41 weeks gestation. The growth rate of the femur length has also been calculated (1.63 mm/wk), and that of the biparietal diameter was 1.59 mm/wk. With the use of these data, the error in estimation of gestational age given by femur length is 11 days, and by biparietal diameter one is 14 days. Fetal femur length should be measured rather than biparietal diameter in ultrasound diagnosis of gestation age.
