title: [ASSESSMENT OF THE RESULTS OF CLINICAL AND RADIONUCLIDE STUDIES IN PATIENTS WITH PULMONARY TUBERCULOSIS].
abstract: The paper presents experience with differential radionuclide imaging used to study the extent and activity of a pathological process in the mediastinal lymph nodes and lung tissue in 83 patients with pulmonary tuberculosis. The diagnostic value of a 99-mTc-technetril technique has been established to be similar to that of 67Ga citrate one. The sensitivity of the 99-mTc-technetril technique in a lung tissue inflammation focus was 97.0% and that of the 67Ga citrate technique was 91.5%. That of inflammatory changes in the mediastinal lymph nodes was 95.5 and 98.6%, respectively. Choosing a technique for patients with pulmonary tuberculosis has ascertained that 99-mTc-technetril has a low radiant energy of gamma quanta (140 Kev); a small half-life of 6.2 hours; radiation exposure is reduced 15-fold. The use of 99-mTc-technetril confirms the statement that tuberculosis spreads more commonly by the hematogenous route when the specific process is located in the upper lung and by the lymphatic bronchogeneous route when it is located in the lower lung.
