OBSTETRICAL / FETAL U L T R A S O U N D

What is the purpose of an obstetrical ultrasound exam?

An obstetrical ultrasound exam looks at the uterus and ovaries, and at the fetus. The fetus is checked to be sure that its size is appropriate for its "age." 

What happens during the exam?

The patient lies on a table with the abdominal area exposed. The sonographer (technologist who performs the exam) will put a warm water-based gel on the skin surface. The gel helps to transmit sound waves by excluding air. An instrument called a transducer, which is about the size of a microphone, will be moved over the skin surface by the sonographer.

How do I prepare for this test?

You may eat regular meals prior to an obstetrical ultrasound exam.
