During the last decade, helical CT revolutionized diagnostic imaging. Advanced computational programs now available allow creation of automatic 3D model of the tracheobronchial tree, making possible endotracheal and bronchial navigation similar to real fibrobronchoscopy virtual bronchoscopy (VB) is useful in the study of fixed stenosis of the airway distal to the lesion, something that cannot always be achieved with real fibrobronchoscopy. VB can also show the adjacent mediastinal structures simultaneously represents a great advantage of this technique. If its use gives relevant information for patient management is something yet to demonstrate in prospective studies
