CT结肠成像，也称为虚拟结肠镜检查，大约在十年前引入，多年来取得了很大进展，并且越来越受欢迎。随着CT扫描仪和计算机软件的出现，检查进行得更快，患者辐射暴露更少，为放射科医生提供了使用二维和三维成像进行准确息肉检测的数据。在这篇文章中，我们将回顾CT结肠成像的技术基础，其目前的适应症和性能。
CT colonography, also called virtual colonoscopy, was introduced about a decade ago, has made great progress over the years, and is becoming more popular. With the advent of CT scanners and computer software, the examination is performed more quickly and with less patient radiation exposure providing the radiologist with data that allow for accurate polyp detection using both two-and three-dimensional imaging. In this article we will review the technical basics of CT colonography, its current indications, and performance.
