Virtual colonoscopy is an exciting new imaging technique with potential to
alter current diagnostic approaches to colonic diseases, particularly colon
ic neoplasms. Although colonoscopy continues to offer the highest sensitivi
ty and specificity for evaluation of the colon, virtual colonoscopy may off
er greater safety, less discomfort, and consequently greater patient accept
ance. In addition, virtual colonoscopy offers shorter procedure time, more
accurate lesion location, and potentially lower cost as a screening test. L
imited data are currently available to define virtual colonoscopy's full cl
inical role. This article describes the technical considerations, current c
linical status, limitations, and potential indications of this new and exci
ting technology which gastroenterologists should not fear but embrace. Copy
