Biophysical Studies of the Human Fetus

  • Edward H. Hon

Abstract

Since the human fetus is inaccessible to the usual biochemical methods for assessing the infant or adult, evaluation of its well-being is difficult. Methods for fetal study are, therefore, for the most part, limited to biophysical techniques, except for the later stages of labor when the membranes have been ruptured and cervical dilatation is present.
