Abstract
Computed tomographic colonography (CTC) has emerged as an alternative screening tool for colorectal cancer due to the potential to provide good efficacy combined with greater acceptability than optical colonoscopy or fecal occult blood testing. However, some organizations have raised concerns about the potential harms, including perforation rates and radiation-related cancer risks, and have not recommended that it currently be used as a screening tool in the general population in the US. In this article the authors review the current evidence for these potential harms from CTC and compare them to the potential harms from the alternatives including colonoscopy and double-contrast barium enema.
摘要
计算机断层结肠成像（CTC）已成为一种用于结直肠癌的替代筛查工具，因为它有可能提供良好的效果，并且比光学结肠镜检查或粪便潜血检测具有更高的可接受性。然而，一些组织对其潜在危害表示担忧，包括穿孔率和辐射相关的癌症风险，并且不建议目前在美国普通人群中将其用作筛查工具。在本文中，作者回顾了目前关于CTC这些潜在危害的证据，并将它们与包括结肠镜检查和双对比钡灌肠在内的替代方法的潜在危害进行了比较。
