Utility of the head computerized tomography scan in child and adolescent psychiatry

Despite the widespread use of computerized tomography (CT) in child and adolescent psychiatry, studies have not looked at its overall usefulness in a clinical setting. In this report, the authors examined 122 inpatients who had CT scans of the head. Only 27 patients had an abnormal CT scan. None of the patients had a change made in the diagnosis or treatment as a result of the scan findings. The authors suggest that routine CT scans of the head in child and adolescent inpatients is of limited value. In view of the rising costs of medical investigations, and the risk of irradiation to the developing brain, they suggest the need for clear indications for this procedure in clinical child and adolescent psychiatry.
