[Radionuclide diagnosis of capillary pulmonary blood flow in new cases of pulmonary tuberculosis].

The radionuclide technique pulmonary perfusion scintigraphy was used to study 124 new cases of pulmonary tuberculosis before therapy and 25 controls. The data indicated that perfusion impairments were significant and rather noticeable in 84% of new cases of the disease. Evidence was provided for that pulmonary capillary blood flow was associated with the duration of the disease, with the initial type and phase of a tuberculous process, and with clinical manifestations. There was a predominance of significant and drastically marked vascular lesions in patients with infiltrative and disseminated tuberculosis under the present conditions.
