The purpose of this study was to demonstrate the existing correlation between bronchoscopic examination and helieal computed tomography with three-dimensional reconstructions. Eighteen patients with non-small cell carcinoma of the lung were studied. A good correlation was observed in patients with stenosis of stem and lobar bronchi, either intrinsic or extrinsic. The three-dimensional images reveal the spatial location of the tumoral mass, the alterations of intrathoracic structures, and the lung parenchyma secondary to tumoral growth. The internal and external views of the bronchial tree also correlate well with the bronchoscopic findings and permit visualizations of the airway changes beyond the stricture. In some patients, this information permits better planning of laser therapy and a better understanding of the actual pathology of the neoplastic process. However, the staging and diagnosis of the patients are not substantially modified.
