tracheohronchial reconstruction of helical computed tomography (C.T.). Aiming at assessing the accuracy of helical CT with surface-rendered 3D reconstruction in the evaluation of endobronchial lesions, 3D re constructed images were compared to bronchoscopic findings in 10 patients who underwent both hel ical chest CT and fiberoptic bronchoscopy during clinical evaluation of their thoracic problems. Such simulations showed complete bronchial obstructions by tumours in 6 cases, partial bronchial obstruc tions in Sand extra-luminar compression in one. Not only did simultations accurately represented bron choscopic findings but also added information about distal bronchial lesions that were beyond the bronchoscopist's direct vision. Evolution of faster computers using parallel processing should adress the problem of time consumption and costs facing this recent technology.
