Lung imaging in pulmonary disease
Although it has been recognized for several years that chronic obstructive pulmonary disease (COPD) can cause lung perfusion defects which may simulate pulmonary embolism, relatively little use has been made of either the radioxenon or the radioaerosol inhalation lung imaging procedures until the last few years as a means of distinguishing pulmonary embolism (P.E.) from COPD is reported. Recent experience is reported with the use of both of these procedures in comparison with pulmonary function tests for the early detection of COPD in population studies and also in P.E. suspects. Equal emphasis is given to simultaneous aerosol ventilation-perfusion (V/P) imaging in the differential diagnosis of P.E. Finally, this paper is concerned with new developments in regional lung diffusion imaging following the inhalation of radioactive gases and rapidly absorbed radioaerosols. Their experimental basis is presented and their potential clinical applications in pulmonary embolism are discussed. As a result of these investigations, a functional (V/P) diagnosis of pulmonary embolism in patients may be possible in the near future with a sequential radioaerosol inhalation procedure alone.
