This question deserves a broad answer, considering how much has changed since the old high-resolution CT (HRCT) scans with 1-mm slices and 1-cm intervals. (1-3) The advent of multidetector row CT has had a significant effect on the versatility and diagnostic capabilities of CT in general. Coupled with novel processes of image postprocessing--including quantification of lung disease using advanced software--the availability of multiplanar projections and the opportunity to perform virtual bronchoscopy have led to an improvement in what is available for the evaluation of COPD.

In the workup, physicians choose from a variety of diagnostic methods, depending on the clinical need and circumstances of the patient. COPD is a heterogeneous disease, and what is important for patients with emphysema (quantification and regional assessment of disease or planning of interventional bronchoscopic or surgical procedures such as lung volume reduction surgery) is less relevant for those in whom airways disease and mucous plugging are the dominant features. It may be useful to briefly review the various...
