title: Computed tomography of the lung.
abstract: Preliminary work has shown that normal lungs have predictable CT patterns and density ranges. In emphysema, there are irregular zones of extremely low density as well as an overall low mean density. CT appears to have considerable potential for early detection of pulmonary emphysema and characterization of the degree of involvement. CT can also be useful in the study of physiological phenomena such as regional blood flow.
