简要总结
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.
详细描述
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.

结局指标
主要结局
The growth rate (natural history) of small colorectal polyps
时间窗: 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
