A new method for estimation of fetal weight in late pregnancy by ultrasonic scanning
The biparietal diameter and are of the fetal skull, and the area of the fetal thorax, were measured by ultrasonic scanning in 68 patients in the seven days prior to delivery. These parameters and various expressions based on the skull and thoracic areas were related to birth weight. It was concluded that the skull and thoracic areas multiple (STAM) index was a more efficient predictor of birth weight than the biparietal diameter.
