[Roentgenologically demonstrable changes in pneumoconiosis (author's transl)].

Based on the new international definition of pneumoconiosis the various types of this lesion and their roentgenological appearance are described. The lesions may arise from fibrosis-inducing dusts (silica, asbestos) and also from the deposition of dust particles especially those of high atomic weight. Pneumoconiosis in coal miners, the most common dust-induced lung disease in Germany, is reviewed in detail and the X-ray demonstration of dust in the lungs is discussed.
