Are serial brain imaging scans required for children who have suffered acute intracranial injury secondary to blunt head trauma?

In most instances, infants and children with moderate to severe head trauma undergo a head computed tomography (CT) scan as part of their initial evaluation. Several authors have advocated a routine second head CT after traumatic brain injury (TBI) to identify progressive lesions that may require surgical intervention. However, recent studies have challenged the need for a routine second brain imaging study after TBI.
