Dear AuntMinnie Member,
Computer-aided detection (CAD) has the potential to make virtual colonoscopy a more effective screening tool by making the exam more sensitive and easier to perform. But the technology still has a few kinks to work out, according to a recent story by staff writer Eric Barnes that we’re highlighting this week in our Virtual Colonoscopy Digital Community.
University of Chicago researchers used CAD in an effort to see if the technology could produce better results in a reduced-prep regimen designed to reduce patient discomfort. Such techniques often use fecal tagging to separate stool from possible polyps on images.
The researchers found that CAD produced high sensitivity, but if the dietary-based fecal tagging was incomplete, the CAD produced a large number of false-positives by mistaking stool for polyps. Get the rest of the story in our Virtual Colonoscopy Digital Community, at http://vc.auntminnie.com
