[Dynamic scintigraphy of the lungs with 133Xe in chronic bronchitis].
A method of dynamic scintigraphy with 133Xe was used to study regional ventilation and regional pulmonary blood flow in 58 persons (14 practically healthy persons and 44 patients with chronic bronchitis). The data obtained were assessed visually and subjected to a quantitative processing according to the above-mentioned program. Quantitative distinctions in regional values of the residual volume, a ratio of the residual volume to the general capacity, the time of mixing, a half-period of washing off made it possible to distinguish clearly between two forms of chronic bronchitis (non-obstructive and a form with the noticeable obstructive syndrome). Thus quantitative characteristics added considerably to a visual evaluation of the obtained results.
