Experience in utilizing ultrasonic compound scanning in obstetrics

A promising method of ultrasonic diagnostics is compound or multiple scanning. Its application in obstetrics makes it possible to more distinctly define the contours of the structures studied. Results subsequent to an examination of 750 pregnant women showed that by using this method it becomes possible to determine the position of the fetus, biparietal diameter of its head, the size of the placenta, abnormalities in the development of the fetus, etc. The advantages of compound scanning are particularly spectacular in estimating the growth of the fetal head during early periods of gestation.
