Abstract
Uneven distribution of inhaled aerosol in the lungs is the characteristics of obstructive airways disease such as chronic bronchitis and pulmonary emphysema, and has been classified typically into peripheral and central deposition patterns, respectively by visual inspection, whereas in the normal the distribution is homogeneous throughout the lungs. The purpose of the present study was to analyse the distribution of inhaled radioactivity in the lungs by way of matrixes by a computer. The seemingly homogeneous distribution pattern in normal subjects has been found to indicate a gradual change in count profile between the neighboring matrixes. The peripheral pattern indicates the patchy presence of small number of matrixes with excessive radioactivity throughout the lungs, and the central pattern, the presence of matrixes of excessive radioactivity along the major central airways forming a comma-like configuration superimposed on the peripheral pattern. Our computer analysis has a potentiality to characterize obstructive airways disease for a better understanding of their pathophysiology, which is not feasible by a simple visual inspection of images on a polaroid picture.
