CT scans are a diagnostic procedure, which uses an X-ray beam that rotate around the body. During this rotation, pictures are taken of the body from different views. The computer than converts those various views into a detailed image of the body part. CT scans are a good choice for children, because they are usually quick, noninvasive and an accurate way to help diagnose a problem.
Function
Bones, internal organs and tissue can all be seen in a CT scan. A scan may be performed on your child to help the physician diagnosis conditions such as a tumor, internal bleeding or other injuries. A scan may also be completed to determine if cancer treatment is working. Since CT scans are able to produce more detailed images of the body than an X-ray, they may be done instead.
Types
CT scans may be ordered with or without contrast. Contrast is a dye that helps some body parts be seen more clearly. If contrast is needed, dye may be given intravenously, which can be momentarily painful for your child. Or he may be given contrast orally through a liquid. The oral form of contrast may have a bitter taste and may be difficult to drink, especially for younger children.
Sedation
To get accurate pictures, children need to stay still during a CT scan. This may be difficult for some children, especially younger ones or children who are in a lot of pain. Depending on the age of the child, sedation may be needed to prevent her from moving too much. If sedation is given, an IV will likely be used to administer the medication. Pay close attention to instructions regarding what your child can eat and drink before the scan if sedation will be used.
Considerations
Depending on the age of your child, there are things you can do to help your child get through a CT scan easier. Explaining the procedure to your child in advance and if possible taking him to see the CT room may help ease fears. Although hospital polices vary, you may be able to stay with your child during the CT scan, which may ease fears. It may also help your child to bring a comfort item, such as a favorite blanket, to the scan.
Risks
According to RadiologyInfo.org, although radiation is used, the benefits of a CT scan often outweigh the small risk associated with radiation exposure. Children wear a shield over the parts of the body that are not being scanned to protect them from radiation. Although uncommon, allergic reactions to the contrast given prior to the scan can happen. Some children may also be sensitive to the medication given for sedation, which can cause complications.
