Abstract

The method of radiographic diagnosis of pneumoconiosis has been internationally standardized; namely, each film is evaluated according to the profusion, shape, and size of small opacities with reference to preselected standard X-ray films of typical pneumoconiosis [1, 2]. Recently, new diagnostic technologies such as computed tomography (CT) have been introduced, although they are still in the experimental stage [3–5]. In this chapter, we report the results of an objective study performed by many specialists on the applicability of the computed radiography (CR) system in the diagnosis of pneumoconiosis, a field which has a long history.
