title: Computed tomography of the lung. Densitometric studies.
abstract: This discussion summarizes the physical basis for CT densitometry, the methods used for extracting density information from CT scans, and how the CT scanner has been used to noninvasively monitor the changes in the major mass and volume components that determine lung density (gas, vascular, and extravascular volumes).
