title: ACR Appropriateness Criteria on chronic dyspnea: suspected pulmonary origin.
abstract: Chronic dyspnea of pulmonary origin raises concern for chronic obstructive pulmonary disease or interstitial lung disease. A chest radiograph is recommended as the initial imaging study. When chest radiography is nonrevealing or provides no definitive diagnosis, a high-resolution chest computed tomography is indicated. The high-resolution chest computed tomography should include expiratory imaging in patients with known or suspected air trapping.
