Radioaerosol inhalation lung cine-scintigraphy: a preliminary report.

"Radioaerosol inhalation lung cine-scintigraphy", a cinematographic display of the lungs following radioaerosol inhalation has been found to be extremely helpful not only to the visual assessment of mucociliary clearance in the lungs but also to the setting of regions of interest and to the interpretation and analysis of clearance curves over the regions of interest in the lungs. It is expected that this procedure offers an important means to the study of mucociliary clearance in health and disease in man.
