title: [Computed tomography in the evaluation of regional metastases of lung cancer].
abstract: The rate of metastatic spread of different groups of intrathoracic lymph nodes has been studied in depending on localization of the tumor by the nodes using CT method. 126 patients were examined with verified diagnosis of lung cancer. The central form was diagnosed in 55 (43.6%) patients, peripheral--in 71 (56.4%), a tumor was located in the upper lobe in 72 (57.1%), in the lower lobe--in 47 (37.4%), and in the middle lobe--in 7 (5.5%). CT-semiotic of metastatic lymph nodes was studied. The indices of the efficiency of diagnostic imaging when using CT were analyzed as well. The analysis of data obtained has shown that CT has great possibilities in evaluation of regional metastases of lung cancer.
