Virtual Colonoscopy (VC) for Primary Colorectal Screening
CT Virtual Colonoscopy for Primary Colorectal Screening
This study involves a primary VC screening for colorectal polyps. The research hypothesis is that VC screening, including surveillance of sub-cm polyps, is a safe and effective approach.
The purpose of this study is to use virtual colonoscopy screening to learn more about what happens to small colon polyps (less than 10 mm) over time. From this, we can find out whether it's safer to remove all colon polyps right away or leave the small ones in place and remove only those that grow to 10 mm or more.
