ABSTRACT
OBJECT To evaluate changes in the diameter of bronchi and pulmonary arteries during respiration. MATERIALS AND METHODS:
The ratio of the diameter of matched inner bronchi and accompanying pulmonary arteries was calculated from full inspiration and expiration HRCT of healthy men.RESULTS:
In 106 pairs of matched bronchi and pulmonary arteries, the brohchial-arterial ratios were 0.61+/-0.18(upper lung), 0.72+/-0.21(lower lung), and0.65+/-0.20(total) at full inspiration and 0.51+/-0.32(upper lung), 0.52+/-0.15(lower lung), and 0.51+/-0.26(total) atfull expiration HRCT, denoting a statistically significant increase in bronchial diameter of the entire lung atfull inspiration. The inner diameter of the bronchus was larger than the diameter of the accompanying pulmonary artery by 0.1% at full expiration and 8.5% at full inspiration.CONCLUSION:
The result of this study would be helpful in understanding the physiology of the lung during respiration.
