Abdominal computed tomography scan (CT scan)

This diagnostic imaging procedure uses a combination of X-rays and computer technology to produce comprehensive images of the body (often called cross-sectional images, or “slices”), both horizontally and vertically. CT scans are more comprehensive than general X-rays, and can show details as small as 3-5mm of any part of the body, including the bones, muscles, fat and organs. Your child will lie on a bed that moves into a doughnut-shaped machine that takes many pictures of different areas of the body. CT scans typically require your child to lie still with their arms over the head for some time. Occasionally, doctors might give a sedative to help your child rest through the duration of the procedure.
