For several years the distinction between normal and pathologic lymphnodes was based on the dimensional criteria (radiological diameter more than 1 cm). Computed tomography is valuable for the assessment of hilar and mediastinal lymphnodes. The aim of this study is to report the specificity and the sensitivity of CT in the evaluation of mediastinal lymphnodes in non-small cell lung cancer and to identify the indications for the preoperatory mediastinoscopy. The CT showed low sensitivity and high specificity for the assessment of mediastinal lymphnodes.

Abstract
For several years the distinction between normal and pathologic lymphnodes was based on the dimensional criteria (radiological diameter more than 1 cm). Computed tomography is valuable for the assessment of hilar and mediastinal lymphnodes. The aim of this study is to report the specificity and the sensitivity of CT in the evaluation of mediastinal lymphnodes in non-small cell lung cancer and to identify the indications for the preoperatory mediastinoscopy. The CT showed low sensitivity and high specificity for the assessment of mediastinal lymphnodes.
