Rationale: Computerized tomography is a method of body section radiography. The beam is fo-cused and does not scatter, as with x-rays. It is a noninvasive procedure, causing no pain. Al-though the client must lie still, the procedure rarely takes longer than 10 minutes. Sedation is not required unless the client is a child, confused, or in some way unable to cooperate. The equipment is open and does not cause claustrophobia, as with a MRI procedure. The use of contrast media for head scans does not require fasting; it uses an intravenous site with a small-bore catheter, which can be maintained as needed after the scan—there is no need for ice at the site. (Intestinal preparation may require fasting.) Although metal objects in the hair (such as clips or bobby pins) and wigs need to be removed for clear pictures, metal does not cause a hazard.
