ABSTRACT
Scintigraphic evaluation of 67Ga citrate was made in 102 patients with diffuse pulmonary lesions (DPL) of various genesis. There was respiratory sarcoidosis in 40 patients, exogenous allergic alveolitis in 47, idiopathic fibrosing alveolitis in 3, histiocytosis X in 6, and carcinomatosis in 6. Radionuclide findings indicated that the radioagent accumulated in intrathoracic lymph nodes of the mediastinum and partially in the lung tissue in 75.5% of cases at the acute stage of the disease, negative results were in 24.5%, as explained by the fact that the studies were conducted at remission or in the presence of pneumosclerosis. Reexaminations of DPL patients using 67Ga citrate may yield objective information on the treatment performed and, if the latter fails, correct it.
