Abstract: | An investigation was carried out to show whether lay readers could be trained to interpret chest radiographs for coal workers' pneumoconiosis. It was shown, first, that lay readers can be trained for this purpose, and second, that they are no more prone to interobserver variation than are physicians. Once again, the extent of the interobserver variation among experienced readers in the categorization of the films for coal workers' pneumoconiosis was shown to be greater than is commonly realized. |
