| Abstract | [Summary] A new modality of display following radioaerosol inhalation which we call "radioaerosol inhalation lung cine-scintigraphy" or "aerosol inhalation cine-scintigraphy" in short has enabled us to visualize the movement of inhaled radioactivity after its deposition in the lungs and allowed us to assess mucociliary clearance mechanism more directly and accurately than by any other means as far described. Mucociliary clearance is usually cephalad in direction from peripherally to proximally, but pathologic conditions such as pulmonary emphysema or bronchogenic carcinoma could not only retard or stop the clearance but also drive radioactivity transported from one lung into the opposite side or even retrogress the mucus flow. Radioaerosol inhalation lung cine-scintigraphy has also helped to select the regions of interest to get regional clearance curves and to interpret the meaning of each clearance curve thus obtained. This new modality is expected to serve as an indispensable means to study mucociliary clearance mechanism, a potentially important non-respiratory function of the lungs. |
