This book represents a new approach to diagnostic roentgenology. The material is organized by type of x-ray appearance, the objective findings as seen on roentgenograms, rather than by disease. By this method the reader is lead to organized thinking in the analysis of the roentgenographic findings and to a consideration of them in a differential manner, prior to arriving at a definite interpretation. In developing this type of approach, the author discusses the technical aspects, including positioning of the patient, exposures, contrast material, and the anatomy of the body region. For each disorder there is a clear, concise discussion of the roentgenographic appearance, pathological physiology of the lesion as it affects the appearance on the film, and the features that serve to aid in differentiating a particular disease from another.
