Abstract
The invention and rapid development of computerized tomography is one of the major medical advances of our time. Current multidetector CT scanners can image the entire chest in 2–5 s, producing up to 1,000 slices, each composed of sub-millimeter isometric voxels. These high signal-to-noise ratio, large field-of-view images provide non-invasive anatomic evaluation of the chest with similar information content to that achievable at autopsy. In vivo physiologic functional information regarding the pulmonary vasculature, systemic vasculature or airways can be obtained by acquiring CT images while administering intravenous contrast media or performing breathing maneuvers, respectively. Expert radiological interpretation of these volume data sets can differentiate diseases that are clinically indistinguishable, but demonstrate unique changes at the gross anatomic level.
