CT scans have revolutionized medical diagnosis but their radiation may increase the risk of cancer, especially in children.

Now a study in the journal Pediatrics aims to help reduce unnecessary exposure. It says children brought to emergency rooms with minor head injuries should be screened before doctors decide to give them CT scans.

Researchers found that four to six hours of clinical observation significantly reduced the use of CT scans in children with minor trauma. The watching and waiting also minimized chances that a serious head injury would be overlooked.
