It is not a complete treatise on pneumoconiosis. Many phases of the problem of silicosis, asbestosis, and coal workers' pneumoconiosis are not considered. The effort has been directed largely toward a discussion of guide lines helpful in the interpretation of shadow patterns in the roentgenograms. These were gathered from records of silicosis in some 500 workers in industry who were exposed to free silica with essentially no contaminating dust. Many cases were followed up for over 20 years.

This book is aimed at interesting more radiologists in pneumoconiosis. The radiologist not only plays an important role in the diagnosis but also has increased opportunities for estimating pulmonary disability and complementing pulmonary physiological studies. The specific lesions of the three pneumoconioses are described, with
