The role of radiology in the management of patients with a history of ingested foreign bodies is reviewed in a retrospective study over a 2-year period in a Children's Hospital. If radiography was confined to those children who have a clinical history suggestive of foreign body impaction in the oesophagus, a foreign body aspiration or having swallowed a button battery, the work load and unnecessary radiation arising from this practice could be halved. This study demonstrates another misuse of radiological services.
