Chronic obstructive pulmonary disease (COPD) is a disease in which the airways and tiny air sacs (alveoli) inside the lungs are partially obstructed or destroyed. Emphysema is what occurs as more and more of the walls between air sacs get destroyed. Computed tomography (CT) image has been a useful modality for assessing diffuse lung diseases, particularly, emphysema. At present, diagnosis of emphysema...

Chronic Obstructive Pulmonary Disease (COPD) is a disease in which the airways and tiny air sacs (alveoli) inside the lungs are partially obstructed or destroyed. The result is labored breathing. There are varying degrees of this illness, and different names for them, but it all comes back to damaged airways and air sacs. Emphysema is what occurs as more and more of the walls between air sacs get...
Emphysema is characterized by loss of elasticity of the lung tissue; destruction of structures supporting the alveoli; the destruction of capillaries feeding the alveoli. The result is that the small airways collapse during expiration, leading to an obstructive form of lung disease (air is trapped in the lungs in obstructive lung diseases). The scientific definition of emphysema is: "permanent...
