The use of ultrasound in obstetrics and gynecology.

Advantages of ultrasound as a diagnostic tool are many. The patient experiences no discomfort, nor does she feel any sensation. The patient can be examined without moving from her bed. Unlike x-ray, there is no danger of exposing the fetus and the mother to adverse effects of radiation. Its application in determination of fetal death, early in pregnancy, diagnosis of hydatidiform mole and localization of the placenta in cases of antepartum hemorrhage are only some of the obvious applications of this method.
