Virtual colonoscopy: past, present, and future

Radiol Clin North Am. 2003 Mar;41(2):377-93. doi: 10.1016/s0033-8389(02)00124-0.


Virtual colonoscopy is developing into a practical clinical technique. The issues of the steep learning curve and accuracy of the technique are undergoing advances related to patient preparation, scanning technique, reading methods, and CAD. It is probably the best test for patients with an incomplete colonoscopy or for those patients who cannot undergo colonoscopy. Its precise role in screening average-risk patients for colon cancer remains to be defined by ongoing research and clinical trials.
