Transmission-emission pulmoscintigraphy in the diagnosis of pulmonary diseases

The potentialities of transmiission-emission scintigraphy in the diagnosis of pulmonary diseases were studied. Thirty-eight patients were examined using transmission positive scintigraphy and 85 patients using transmission-perfusion pulmoscintigraphy. An analysis of the results obtained showed that a combined use of positive and transmission pulmoscintigraphy was a simple and available method providing a full-value idea of the anatomotopographic interrelationships of a tumor lesion and the surrounding tissues. A combined use of transmission and perfusion pulmoscintigraphy considerably expanded the diagnostic potentialities of the latter permitting accurate estimation of the volume of perfusion disorders in the lungs. The above method allows one to objectivize the estimation of positive and perfusion pulmoscintigrams
