The presence of dilatation of the right descending pulmonary artery is a reliable roentgenologic sign of pulmonary hypertension, though no linear correlation exists between pulmonary artery widths and pulmonary artery pressure. And so, at the first, the author measured the right descending pulmonary artery on both inspiratory and expiratory chest roentgenograms of 200 normal male adults and 200 normal female adults, using Chang's method, to obtain normal value of measurements in Koreans. The results were as follows: 1. In males, the range of the right descending pulmonary artery measurements was 9-16mm. in inspiration and 8-15mm. in expiration. The mean inspiratory measurements was 14.0mm. as compared to 12.1mm. for the expiratory measurement. the range of difference between inspiratory and expiratory measurements was 103mm. (1mm. in 44 cases, 2mm. in 138 cases, and 3mm. in 18 cases). The mean difference was 1.9mm. 2. In females, the range of measurement of the right descendin pulmonary artery was 9-16mm. with a mean measurement of 12.9mm. in inspiration. The expiratory measurements showed a range of 8-14mm., with a mean measurement of 11.1mm. the range of difference between inspiratory and expiratory measurements was 1-3mm. (1mm, in 62 cases 2mm. in 114 cases and 3mm. in 24 cases). The mean difference was 1.8mm. 3. There are apparent changes in the measurement of the right descending pulmonary artery during respiration in normal adults. The size of the right descending pulmonary artery increases during inspiration and decreases during expiration. There were 103mm. differences between inspiratory and expiratory measurements. In 252 cases (63%), the difference was 2mm.
