The intrareader and interreader variability of both Chinese and American pneumoconiosis readers was evaluated, and the interpretations on a set of films by the Chinese readers using the 1986 Chinese Roentgenodiagnostic Criteria of Pneumoconioses were compared with American interpretations on the same set of films using the International Labour Office (ILO) classification. The films included 150 posterior/anterior chest X-rays; half were Chinese X-rays of silica exposed workers showing abnormalities, and half were American X-rays of exposed workers, including coal miners, showing a range of abnormalities. There were 12 Chinese and three American readers participating in the study. While some variability was noted among the 12 Chinese radiologists, there was general agreement among them. In general there was a tendency for Chinese readers to read more pneumoconiosis than the American readers. The agreement in detecting pleural abnormalities was 89%. As with pneumoconiosis detection, again the Chinese radiologists described more abnormalities than their American counterparts. Agreement in cancer detection was also good. The authors conclude that a valid correspondence exists between the Chinese and American interpretations, in spite of using different classification systems.
