Ultrasonographic measurements of fetal femur length and biparietal diameter in an Israeli population

Background: Charts of fetal measurements are widely used in the follow-up o f pregnant women, however no charts have been constructed for the Israeli p opulation. Objectives: To establish growth charts for fetal femur size and biparietal diameter, Methods: A prospective cross-sectional study of 1,422 singleton pregnancies was conducted. Results: A total of 1,143 pregnancies met the inclusion criteria, Femur len gth and biparietal diameter were measured. A linear cubic model was fitted to construct growth charts for the different centiles. The charts were comp ared with previously published data. Conclusions: We have constructed new fetal measurement charts for femur len gth and biparietal diameter that are unique for the Israeli population, The se charts have been found to be similar to those published for other Caucas ian populations.
