Open-source software increases colon polyp conspicuity
By Eric Barnes
Visibility of colon polyps is increased and sensitivity improved with the use of threshold-based color-coding software in virtual colonoscopy, according to a new study from Italy. Even flat lesions were more often visible with use of the open-source 2D-based interpretation software.

Blood infection risk extremely low with VC
By Eric Barnes
The risk of bloodstream infections such as bacteremia leading to endocarditis is extremely low in virtual colonoscopy -- in fact, infection rates are probably even lower than in conventional colonoscopy, say researchers from Ireland, the U.K., and the U.S.
