Angiocardiography, with 70 % sodium acetrizoate as the contrast medium, has been carried out in more than 600 patients with pulmonary disease without a single fatality. It permits the visualization of the lobar and segmental branches of the pulmonary arteries and thus reveals conditions that often escape detection by other diagnostic methods. Seven cases are reported illustrating its usefulness in distinguishing between vascular and nonvascular lesions and its importance in deciding between surgical and medical treatment. It is essential for the diagnosis of pulmonary arteriovenous fistula and helpful in evaluating thoracoplasties. The author believes that it should be more frequently employed in the study of pulmonary diseases.
