[Scintigraphic evaluation of pulmonary microcirculatory bed and intrathoracic lymph nodes in patients with infiltrative tuberculosis].

Complex radionuclide study was conducted in 134 patients with infiltrative tuberculosis. According to the extent and severity of a specific process in the lung, all the patients were divided into two groups. Group 1 comprised 43 patients and group 2 included 91. Radionuclide studies were made according to two parameters: the activity of dysfunction of intrathoracic lymph nodes (ITLN) in the mediastinum with Ga-67 citrate and the magnitude of pulmonary regional circulatory disorders. The results of radionuclide studies in patients with infiltrative pulmonary tuberculosis indicated that not only a lung tissue inflammatory response, but also the development of pneumosclerotic changes both at the site of the basic specific process and in the intact area are responsible for regional circulatory disorders. The absorption uptake of Ga-67 citrate in the mediastinal lymph nodes and in the inflamed lung tissue areas varied with the process of chemotherapy and the beginning of a radionuclide study.
