Abstract

Virtual bronchoscopy is still in its infancy, having been initially described in 1993. The technical aspects of data acquisition are still being refined and will continue to develop with advances in computer and scanner technology. Common current scanning protocols include spiral scanning with 3-mmcollimation and a pitch of 1, with the scan volume starting at the top of the aortic arch and extending inferiorly for a single breath hold. Images are typically displayed on an independent workstation using custom or commercial software. Both surface and volume rendering are being utilized to produce virtual bronchoscopy. Virtual endoscopy in general is finding applications in screening and surgical planning. The clearest potential applicationsof virtual bronchoscopy are in fiberoptic bronchoscopy planning and guidance, and these are likely to drive its development, The three-dimensional images provided may allow better communication of the extent and distributionof mediastinal disease. The utility of virtual bronchoscopy as a diagnostic tool is less certain. Any advantages over axial CT must be proven and mayrelate to specific clinical circumstances. Teaching and training applications will continue to develop and must be tested. Limitations of virtual bronchoscopy are being identified and potential solutions developed. Particularly, the process must become more automated and accurate and less time consuming. As hardware ability to provide data overwhelms human ability to thoroughly evaluate it, virtual bronchoscopy and other computer assistance techniques may become more important. It certainly does not represent a replacement for fiberoptic bronchoscopy, but rather an adjunct. Though many limitations remain, virtual bronchoscopy is likely to prove a valuable tool in directing and improving patient care.
