Gallium-67 thoracic scan and pleural disease in asbestos workers.
We have recently reported that 67Ga scanning in asbestos workers can document excessive uptake of the marker among workers without sufficient criteria for asbestosis, but in our initial report we could not exclude definitely that 67Ga uptake could be related to pleural disease. To further test this hypothesis, we analyzed the 67Ga thoracic scan in relation to profusion scores of pleural disease on chest roentgenogram and CT scan of the thorax in 171 asbestos workers. We found no significant correlation between the 67Ga lung uptake and the radiographic scores of pleural disease. We concluded that pleural plaques are not an active site of 67Ga accumulation and do not contribute significantly to the thoracic uptake of the marker.
