Lung scanning with 67gallium citrate for detection of acute radiation changes.

Radiogallium imaging plays a growing role in the investigation of acute and chronic inflammatory diseases of the lung. We studied a series of patients undergoing radiation treatment for carcinoma of the breast to evaluate the usefulness of imaging with 67gallium citrate in the detection of early radiation changes in the pulmonary parenchyma. In a series of 12 patients there was no correlation between the clinical and radiographic manifestations of radiation pneumonitis and the gallium scan.
