Virtual bronchoscopy

Flexible bronchoscopy represents a clinically well-established invasive dia gnostic tool. Virtual bronchoscopies, calculated from thin-slice CT section s, allow astonishing immitations of reality although principal differences exist between both technologies: the fact that colour representation is art ificial and concommitant interventions are impossible limits the clinical u se of virtual bronchoscopy. However, its value increases when calculations can be attained within minutes due to techonological advancements, and when virtually any chest CT is suitable for futher postprocessing. Indications, findings and the clinical role of virtual bronchoscopy are discussed.
