Clinical Application and Significance of Lung Scintigrams on Pulmonary Diseases such as Pulmonary Tuberculosis

Abstract

We induced unilateral pulmonary function test by means of devided ventilation using carleus tube.
The following results were obtained.
1) Decrease in pulmonary blood flow on pulmonary tuberculosis was demonstrated by lung scintigram method using ¹³¹IMAA.
2) The response occured in some definite conditions. It is a useful complementary method of the roentgen-diagnosis of thorax.
3) Regional vasoconstriction in hypoxic lung area reduce the pulmonary blood flow.
