OBJECTIVE. The purpose of this pictorial essay is to review the current role of virtual bronchoscopy and 3D imaging of the airways in clinical practice.

CONCLUSIONS. Virtual bronchoscopy produces high-resolution images of the tracheobronchial tree and endobronchial views that simulate the findings at conventional bronchoscopy. Interest in virtual bronchoscopy is increasing as a result of improvements in computer hardware and software and advances in MDCT that allow acquisition of isotropic data.

Keywords: airways • CT • virtual bronchoscopy
