PULMONARY CONCENTRATION OF Ga⁶⁷ IN PNEUMOCONIOSIS

Abstract

Thirty patients with overt, well documented pneumoconiosis (24 silicosis, 6 asbestosis) were studied with gallium 67 scans of the lungs and compared with normal controls without lung disease. Gallium 67 concentration was abnormally increased in all pneumoconiosis cases. In one-third of the patients, the spatial extent of gallium 67 uptake was substantially greater than that of roentgenographic abnormalities.
