Estimation of fetal weight by fetography.
The present studies were designed to estimate fetal weight on the basis of the thesis that the factors which determine body weight include the fetal bone and the amount of fetal soft tissue, i.e., fetal corpulence. Scalp thickness on the fetogram in the vertex presentation was measured, and the ratio of the minimal femur diameter to the thickness of soft tissue on the extensor side in the same region was calculated as an index of fetal corpulence. The scalp thickness and the ratio obtained proved to be highly correlated with fetal weight.
