Abstract :In this longitudinal study, fetal bipariétal diameters insert ignore into journalissuearticles values(BPD);, femur length insert ignore into journalissuearticles values(FL);, abdominal circumference insert ignore into journalissuearticles values(AC);, head circumference insert ignore into journalissuearticles values(HC);, mean head diameters insert ignore into journalissuearticles values(MHD);, mean abdominal diameters insert ignore into journalissuearticles values(MAD);, humerus length insert ignore into journalissuearticles values(HL);, and biocular diameters insert ignore into journalissuearticles values(BOD); were measured ultrasonographically between 14-41 weeks` gestation in 30 normal fetuses. By using multiple regression analyses, gestational age prediction curves were constructed for each parameter and evaluated in regard to other data. The comparison of our gestational age curves for BPD, AC, and HC were in good agreement with the results presented by Hadlock et al, and for FL, HL and BOD with Jeanty et al. The differences between our values and the data for MHD and MAD were great especially in the third trimester, approaching 2.6 weeks on the average. These differences in the tables may result from different population studies, genetic variations or from technical errors. It is concluded that, for the establishment of gestational age, new nomograms should be constructed for each fetal parameter, considering the differences presented in this preliminary study.
