The use of physiological tests to differentiate the varieties of chronic pulmonary disease has created more confusion and controversy than it has dispelled. Because these diseases are structurally distinct, anatomic characterization is logical and practical for postmortem studies. Anatomic studies in living subjects almost always use roentgenographic methods. However, methods using routine inspiratory posteroanterior chest roentgenograms have been useful thus far only to recognize emphysema, not to distinguish between types (1).
Nakamura and colleagues (2) have proposed a radiographic procedure called selective alveolo-bronchography to differentiate the types of emphysema during life. The procedure has two distinctive features. First, a contrast
