ACR Appropriateness Criteria® on Chronic Dyspnea

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.
