[Quantitative lung perfusion scintigraphy in lung function diagnosis].
A new method is described for quantitative evaluation in lung perfusion scintigraphy, which allows to conclude from the increased perfusion of normal lung-tissue to a virtual total lung perfusion. The relationship between this and the real total lung perfusion leads to the pulmonary perfusion defects in per cent. The findings of a comparison of 40 patients between the perfusion scan method and the lung function tests is presented, which proves the validity of the new method. It is shown that restrictive lung diseases have a good and obstructive have a bad correlation. It is demonstrated furthermore that the perfusion defects of bronchogenic carcinoma can be quantified very well by the method.
