DIAGNOSTIC TECHNIQUE FOR INFILTRATIVE PULMONARY TUBERCULOSIS ACCOMPANYING CHRONIC OBSTRUCTIVE PULMONARY DISEASE Russian patent published in 2015 - IPC A61B6/00 A61K51/12 

FIELD: medicine.

SUBSTANCE: ventilation-perfusion pulmonary scintigraphy is performed to measure a ventilation-perfusion ratio and an alveolar capillary permeability. Apical and basal perfusion and ventilation gradients of both lungs in a posterior frontal projection are additionally determined. If the normal ventilation-perfusion ratio combines with the high alveolar capillary permeability of inhaled radioactive aerosol for each lung of not less than 30% 10 minutes after the inhalation, and 48% and more 30 minutes after the inhalation, as well as with the apical and basal perfusion and ventilation gradients of 0.70 or lower for each lung, infiltrative pulmonary tuberculosis accompanying chronic obstructive pulmonary disease is diagnosed.

EFFECT: higher diagnostic accuracy for minor forms of tuberculosis accompanying the above pulmonary pathology.
