The size of the lymph node image is an important factor in computed tomographic evaluation of mediastinal lymph node involvement. CT images were retrospectively reviewed in 188 patients with primary lung cancer who underwent pulmonary resection. Comparing the lymph node size in CT images with the result of the histological confirmation, the sensitivity and the specificity were calculated as the functions of the threshold for the diagnosis. The calculated curves of the sensitivity and the specificity showed that the diagnostic capability of CT scan differs, depending on the lymph node location and the histological type of lung cancer. The most adequate threshold for the diagnosis varies according to the clinical purpose of CT diagnosis. Methods for obtaining the most adequate threshold were investigated, and on the basis of the actual sensitivity and specificity curves, it was attempted to calculate the most adequate thresholds for certain determined clinical purposes.
