To produce cross-sectional images of various layers of tissue generating images not readily seen on standard X-rays

Make sure that the consent form is signed by the child’s parents or legal guardians.

Note and report all allergies.

Check the child’s history for hypersensitivity to shellfish, iodine, or iodinated contrast media, and document such reactions on his chart.

Show the child a picture of the computed tomography (CT) machine to help alleviate his fears. (It may be necessary to premedicate the child.)

Explain that the child won’t be able to eat or drink for 4 hours before the scan (depending on age).

The specific type of CT scan dictates the need for an oral or I.V. contrast medium.

Explain to the child that he may experience discomfort from the needle puncture and a warm or flushed feeling from an I.V. contrast medium, if used.

Instruct the child to remain still during the test because movement can limit the accuracy of results.

Tell the child that he may hear a clicking noise as the scanner moves around his head but that the machine won’t touch him.

Tell the child he may experience minimal discomfort because of lying still.

Tell the child to immediately report feelings of nausea, vomiting, dizziness, headache, itching, or hives.

Inform the child and his parents that the study takes from 5 minutes to 1 hour depending on the type of CT scan and his ability to remain still.

A CT scan usually isn’t recommended during pregnancy because of potential risk to the fetus.

The child is positioned on an adjustable table inside a scanning gantry.
