Abstract:
Study on the correlation between the femur length and gestational age from 14-30 weeks. Determination of numeric value table of femur length in correlation with centesimal line 5, 10, 50, 90 and 95 to make a basis to built fetus’s femur length chart, applying to monitor normal or malformation status of fetus. The results: fetus’femur length have a closely correlation with gestational age belong to a second-class function: y = 0.0019x2 +0.2377x + 11.1892, r = 0.97, in which, x = gestational age, y = femur length. Based on this chart, the accuracy of the dating random error about 1 week. The earlier, the estimation of gestational age, the more accurate
