This article reviews the radiologic manifestations and complications of chronic obstructive pulmonary disease, particularly those seen in association with emphysema. Current concepts on the pathogenesis of chronic obstructive pulmonary disease are discussed and related to findings on high-resolution CT scan and histologic examinations. Controversial issues concerning the detection and grading of emphysema using radiologic and physiologic tests are also addressed.
