Our ten years experience on radiologic-pathologic correlations of the lung specimens has proven useful for accurate interpretation of chest radiogram and CT with diffuse lung diseases. The studies are divided into four contents as follows. (1) Preparation of lung specimens and methods of analyzing them (2) Normal roentgen anatomy of the lung (3) Radiologic-pathologic correlation of diffuse pulmonary diseases (4) Interpretation of chest radiogram and CT of diffuse lung diseases based on the above studies This article deals with the first two. The lung obtained at autopsy was inflated and fixed with liquid fixatives. After fixation the lung was sliced and dried for stereomicroscopic and radiographic studies. Five mm thick slices were useful for reconstruct the major bronchi and vessels, while one mm thick slices were suitable for peripheral structures. Three surfaces and margins were noted on the lung. Special attention was paid to the grooves for superior vena cava and aorta and to crista pulmonis to understand normal chest radiogram. In the sliced lung specimens it was noted that pulmonary arteries and bronchi run together, while pulmonary veins are away from these structures. This was recognized both at segmental and lobular level.
