AMBULATORY CARE:
What you need to know about a computed tomography (CT) scan:
A CT scan uses x-rays to take pictures of your child's blood vessels, tissues, bones, or organs. It is also called a computerized axial tomography (CAT) scan.
How to prepare your child for a CT scan:
- Your child's healthcare provider will tell you how to prepare your child. You may be told not to let your child eat or drink anything for 2 to 4 hours before the scan.
- Tell the provider about all your child's allergies. Contrast liquid may be used to help a body part show up better. Tell the provider if your child has ever had an allergic reaction to contrast liquid.
- Tell the provider about all your child's current medicines. The provider will tell you if your child needs to stop any medicine for the scan, and when to stop. The provider will tell you which medicines to give or not give your child on the day of the scan.
- Tell the provider if you know or think your adolescent is pregnant. A CT scan may harm an unborn baby.
What will happen during a CT scan:
Your child will lie face up on a table. Medicine may be given to help your child feel calm and relaxed. Contrast liquid may be given. The table will be moved into an open space in the middle of the machine. Your child will need to lie still during the CT scan. The scan may take 5 to 45 minutes, depending on the type of scan your child needs.
