Rationale and Comments
While CT scans can be a helpful adjunct to diagnosing traumatic injuries, their usage should be tailored to the mechanism of injury and clinical findings. Radiation from CT scans places children at a low but real risk of developing potentially fatal malignancies later in life. Decision rules have been developed to guide the judicious use of CT scans for evaluating traumatic head, cervical spine, chest, and abdominal/pelvic injuries. Chest CTs, in particular, have limited value in the evaluation of pediatric patients with blunt trauma as few findings require specific treatments that change management. Adherence to published guidelines helps reduce unnecessary scans and reduce costs while minimizing significant missed injuries.
