An
ultrasound scan uses sound waves (that the human ear cannot hear) to form
images of the inside of the body. The examination is performed by a Sonographer
(someone who is trained in ultrasound scanning) and varies in time depending on
the region being scanned – usually about half an hour. There
is no ionizing radiation (e.g. X-rays) used in Ultrasound.
Why does my child need an ultrasound?
Ultrasound
examinations can be performed on many parts of the body and are performed for
different reasons, for example to:
- look at the shape or
structure of parts of the body
- check for any signs of
disease
- help plan follow-up
treatment after a procedure
- help with planning before
an operation
- for early detection, treatment,
and management of diseases
Preparing your child for
their appointment
For some ideas on how to
prepare your child for the procedure, and tips on distracting them and helping
them stay calm during the procedure, see our fact sheet Reducing your child's discomfort
during procedures.
It may
be helpful to your child if the procedure is explained to
them before they come in for their
important. Explain that:
- the scans are painless
-
a parent or carer can stay with the
child during the scan
Most children can
watch TV or a movie while having their scans, and you are
welcome to bring in your child's favourite toy, electronic
device or book to keep your child occupied and distracted during the
scan.
Specialist
staff from Child
Life Therapy
may also be of benefit for your child. The Child Life Therapist engages
families in imaging-specific education and medical play, as well as providing
distraction and support during procedures. Appointments for Child Life
Therapist support can be made in advance via Medical Imaging or your referring
doctor.
What to expect with an ultrasound
Before
the ultrasound
It
is very important to make sure you follow the preparation instructions on your
child’s appointment letter, even if you have had an ultrasound before. The
preparation required differs depending on which part of the body is being examined.
If
you have any questions about fasting, drinking fluids, or any other instructions
please call RCH Medical Imaging on 03 9345 6780.
During
the ultrasound
For
all examinations, a family member or carer is encouraged to stay with your
child to help them feel comfortable about the procedure and to help them to
keep still. The scan is performed with your child lying on an examination bed and
either on their back, side or stomach. Your child may need to remove some
clothing depending on the area of the body that is being scanned.
The
Sonographer will place the ultrasound camera on the skin. Special ultrasound
gel is used to help the camera slide across the skin. Many images are taken in
different locations and positions.
After the ultrasound
A report will be prepared by the Radiologist and sent
to the referring doctor. The report is often available within a few days but
can be received earlier if required. If you have any questions about why your
child needs an Ultrasound, or questions about the results of your scan, please
speak to your doctor.
Key points to remember
- Ultrasound is a non-invasive imaging
test that does not use any ionizing radiation
- It is very important to follow your
individual preparation instructions
- A parent or carer is encouraged to
stay with their child during the ultrasound
- You can leave the department
straight after an ultrasound
