Ultrasound

What is an ultrasound?

An ultrasound uses high-frequency sound waves to capture live images of the inside of your body. Ultrasounds are non-invasive and do not hurt your child.

What do I do before the test?

Preparation for your child’s test depends on which part of their body is being scanned.

Some ultrasounds do not require any special preparation, however if pictures of your child’s abdomen are required they will need to fast for four hours before the test.

If pictures of the kidneys or pelvis are required, your child will need to have a full bladder so should be given clear fluids (no carbonated or ‘fizzy’ drinks). You will be told how much they should be given before your appointment.

How are the pictures taken?

The sonographer doing your child’s test will explain it to you and your child in the ultrasound room. The room is dimly lit and there is an ultrasound machine beside the table.

Your child will need to lay down on the table and be very still. You will be able to sit down next to your child. The sonographer will sit down on the other side of the bed and put some warm gel on the part of the body being examined.

A transducer (similar to a microphone) is placed in the gel and moved around the area. The sonographer may ask your child to hold their breath or get into a different position while the images are being taken. The gel does not hurt and is wiped off after the test.

Who looks at the pictures?

One of our paediatric radiologists will look at your child’s pictures and send a report to your child’s referring doctor.

What happens after the test?

The sonographer will let you know when you and your child can leave.

Unless your child’s doctor tells you otherwise, your child can eat and drink normally after their test.

When will I get the results?

One of our radiologists will review the pictures taken during your child’s examination and send a report to your child’s referring doctor. If there is a serious problem that requires treatment, your child’s doctor will be notified before you leave the department.

Your child’s results will be available at their next outpatient clinic appointment or with your referring doctor.

How should I prepare my child?

Infants

To help your baby feel more secure you might like to:

bring along a special toy or dummy
talk to your child during the test
feed your baby after the test
Explain the test to your child just before their appointment as they may become anxious if they are told about it too far in advance.
On the day of the test, let your child know they will be having some pictures taken and tell them that you will stay with them during the test.
Bring their favourite toy or book and a snack for after their test.

Toddlers and preschool aged children
