OBJECTIVE. Virtual bronchoscopy is a new noninvasive technique that provides an internal view of the tracheobronchial tree. The purpose of our study was to assess the role of this technique as compared with fiberoptic bronchoscopy in the evaluation of suspected compression or narrowing of the trachea and main bronchi in children. CONCLUSION. Preliminary results suggest that virtual bronchoscopy may have a useful complementary role to fiberoptic bronchoscopy in evaluation of the tracheobronchial tree of children.
