Gallium scintigraphy in the detection of amiodarone lung toxicity

Fourteen gallium scans were obtained in 11 patients suspected of having amiodarone lung toxicity on the basis of clinical findings, pulmonary function tests, and chest radiographs. All 11 patients had abnormal scans. Gallium accumulates in various inflammatory and neoplastic lesions, but despite this nonspecificity, the findings suggest gallium scintigraphy is a useful procedure to detect amiodarone lung toxicity when used in the appropriate clinical setting.
