What is an Ultrasound?
An ultrasound is an imaging test that uses sound waves to take pictures of organs inside your child's body. It is painless and non-invasive (meaning no cuts or tubes to be inserted). It is often used to assess pain or to detect problems such as enlarged organs.
Getting Ready for the Test
Most ultrasound exams require little or no preparation prior to the exam. Sometimes you may be asked to follow the instructions listed under Ultrasound Exam Preps. It is very important that the instructions are followed closely.
When you arrive at the Radiology Department, one of the sonographers (the person who will be doing your ultrasound) will explain to you and your child how the exam will be done. You will then be taken into a room where you will see a bed and a large ultrasound machine. We encourage parents to sit next to their child during the test.

During the Test
The sonographer will help your child lie on the bed. A small amount of a special warm gel will then be squirted over the part of the body that needs an ultrasound. This gel helps the sound waves go through your child's body and create a picture. Next, a small microphone-like device called a transducer is placed on the body part the doctor wants to look at and your child's pictures are taken. As the pictures are being taken, your child may be asked to lie in different positions. Your child's pictures will be shown to the radiologist (a special ultrasound doctor) who will then decide if more pictures are needed.
The exam will take 30 minutes to an hour.
After the Test
There's a short wait while the pictures are reviewed. Sometimes it may be necessary to take more pictures. When everything is finished, your child will be released. The radiologist will then tell your child's doctor the results of the test.
