Ultrasound

What is an ultrasound?

An ultrasound uses sound waves to make a picture of the inside of the body. You cannot hear these sound waves. It is used to make pictures of soft tissues like the liver or kidneys that don’t show up well on x-rays. It is used to see how blood flows through veins and arteries. This helps to see if there is a blood clot or a defect.

What can I expect when my child has an ultrasound?

• Your child undresses and puts on a gown.
• Your child has to lie still on the ultrasound table.
• The person doing the test will put a warm gel on an area of your child’s skin.
• The person doing the test will use a wand to rub back and forth on your child’s skin.
• Most ultrasound tests last 30 to 35 minutes.
• Ultrasound tests do not hurt.

What do I need to do to help my child get ready?

You get information when you schedule the ultrasound. Information tells you what you need to do to help your child before the test.

• Some tests do not require you to do anything to get your child ready.
• Some tests require your child not eat or drink for a few hours before the test.
• Some tests require your child to drink 2-6 cups of water before the test.

Follow directions carefully. We may not be able to do the test if you do not.
