Brief Summary:
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.

Condition or disease Intervention/treatment
Colorectal Polyps Other: CTC surveillance

Detailed Description:
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.

Group/Cohort Intervention/treatment
In vivo surveillance of 6-9 mm polyps detected at CTC
Other: CTC surveillance
In vivo CTC surveillance of 6-9 mm polyp

Primary Outcome Measures :
  1. The growth rate (natural history) of small colorectal polyps [ Time Frame: The outcome measure of polyp growth rate is established at the time of surveillance CTC by comparing to the baseline CTC ]
    Polyp growth rates are established by comparing polyp volume at the initial and surveillance CTC studies
