Figure 21. Perspective volume rendering of the airways. Axial (top right), coronal (bottom left), and sagittal (bottom right) chest CT scans show a left hilar mass, which is positioned between vascular structures. Virtual bronchoscopy (immersive rendering with a point of view within the tracheobronchial tree) (top left) was used to guide subsequent transbronchial biopsy, allowing six biopsy passes between central vascular structures without significant bleeding.
