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.
肺部慢性呼吸困难引起人们对慢性阻塞性肺疾病或间质性肺疾病的关注。建议将胸部 X 线摄影作为初始影像学研究。当胸部 X 线摄影无明显表现或不能明确诊断时，应进行高分辨率胸部计算机断层扫描。对于已知或疑似存在空气滞留的患者，高分辨率胸部计算机断层扫描应包括呼气成像。
