Obstetric ultrasound refers to the specialized use of sound waves to visualize and thus determine the condition of a pregnant woman and her embryo or fetus. Obstetric ultrasound should be performed only when clinically indicated. Some indications may be:
- To establish the presence of a living embryo/fetus.
- To estimate the age of the pregnancy.
- To diagnose congenital abnormalities.
- To evaluate the position of the fetus.
- To evaluate the position of the placenta.
- To determine if there are multiple pregnancies.
- To determine the amount of amniotic fluid around the fetus.
- To check for opening or shortening of the cervix or mouth of the womb.
