Many brain injuries among children can leave large bruises or even head wounds big enough to require stitches, as some Boston parents may have experienced. But most minor head injuries do really not need a CT scan, which some experts might agree are used too frequently to check on head injuries that are of no risk to the brain.
According to The Boston Globe, a study by the journal Pediatrics indicates the use of CT scans could be reduced by half for kids who have suffered moderate injuries that cause a concussion or vomiting with just careful monitoring for a couple of hours in the emergency room.
