[X-ray-radionuclide diagnosis of lung cancer metastases to the intrathoracic lymph nodes].

The authors conducted a comparative study of x-ray and radionuclide investigations of 203 lung cancer patients. The potentialities of each method were shown for metastatic lesions of the lymph nodes of the root of the lungs and mediastinum. The results obtained are indicative of the fact that these methods improve preoperative diagnosis of regional metastatic spreading in lung cancer that is very important for a design of therapeutic tactics.
