What is CT? CT scans use x-rays generated from the source

that is rotated around the body to create 3 dimensional pictures of the body.

What is an x-ray? An x-ray is a beam of radiation, similar to light,

that can penetrate through the body.

Is radiation harmful to my child? Even small amounts of radiation carry a low risk of

being harmful. The effect of a small amount of radiation is not clearly understood, the doctors assume that it slightly increases the risk of cancer later in life

When radiation is used appropriately, the benefits of a CT scan far exceeds the risks

CT studies can provide critical information for the care of your child, but obtaining the image results in more radiation exposure for the study than a single x-ray.
