Résumé :

Fetal head, chest, and heart cross-sections obtained by ultrasonic diagnostic techniques were used for several measurements: circumference, area, and two diameters, i.e., 3,388 different measurements from 767 healthy fetuses in normal pregnancies. The mean growth for 12 fetal sizes between the nineteenth and the forty-third weeks after the LMP was computed by determining the best adjusted polynomial according to T chebitcheff. Compared with similar measurements made previously by others on premature neonates, the sizes of healthy fetuses of the same gestational age are larger, but almost identical after the thirty-sixth week. Growth standards based on the sizes of premature neonates may be influenced by the factors responsible for premature birth. © 1975.
