Chronic obstructive pulmonary disease (COPD) isn’t a “one-symptom” disease. It used to be thought that COPD was mainly a function of airflow limitation; now it’s well accepted that the disease is made up of a combination of causes and symptoms. Airflow limitation, represented by a measurement called FEV1, used to be the main tool for assessing COPD. Now, not only is FEV1 measured, but also imaging is studied, especially CT (Micro X-ray Computed Tomography). Analysis of a CT-generated three-dimensional perspective of an object’s interior, such as the inside of a lung, can not only help evaluate a patient’s status but can help predict acute exacerbations and aid in a patient’s prognosis.
