Ultrasound – Preganancy

Alternative Names: Obstetric ultrasound, Pelvic ultrasound

A pregnancy, or obstetric, ultrasound is used to examine the abdomen, especially the growing womb (uterus) and foetus. It may be able to detect delayed growth of the foetus and other abnormalities, as well as problems with the placenta. It can also show multiple pregnancies (twins, triplets, etc) and the position of the foetus. Ultrasound is a technique that uses sound waves, which bounce off body structures, to create images on a screen. The test is performed on a full bladder. A simple jelly is placed on the skin of your abdomen and a rounded device (probe), placed against the skin, helps to create the images.

What is it?
Pregnancy ultrasound is an examination of the abdomen, specifically the growing uterus (womb) and foetus, using an ultrasound machine. Ultrasound refers to the use of sound waves, which bounce off (echo) body structures in a manner that can be used to generate images on a screen.

It can be done wherever there is an ultrasound machine and somebody who is trained to use it, but it is most commonly performed in a radiology facility or in your obstetrician’s rooms. It takes about 30 minutes to complete.

Why is it done?
Ultrasounds are performed during pregnancy in order to assess the progress, and health, of the pregnancy. It may be able to detect delayed growth, placental problems, foetal abnormalities, and various other problems. Ultrasound can also detect multiple pregnancies and the position of the foetus.

What happens?

Before – how to prepare
You need to have a full bladder and so you will be asked to drink several glasses of water before the test.

During – how the test is done
You lie on an examination couch and undress sufficiently to expose your abdomen. Some simple jelly (which may be cold) is placed on your skin and the ultrasound probe is then moved over your abdomen to create the images. You may be asked to lie in certain positions to improve the imaging.

After the test
The result will be available almost immediately.
