Plain chest radiography cannot reliably diagnose emphysema in life, but a new method measuring lung density from the computed tomographic CT scan allows location, quantitation, and diagnosis of emphysema defined by enlargement of distal air spaces in humans in life. Hypoventilation in obstructive lung disease. The functional and bronchographic evaluation of postmortem human lungs.
