PURPOSE OF REVIEW
Computed tomographic colonography is a new and noninvasive method to evaluate the colon. The goal of this review is to discuss the latest data and define outstanding issues related to computed tomographic colonography.
RECENT FINDINGS
Computed tomographic colonography is gaining momentum as a potential primary colon cancer screening method in the USA. Although not as accurate as colonoscopy, the accuracy of computed tomographic colonography for detection of large lesions appears to be in the 80-90% range. The field is rapidly evolving, not only in terms of technology but also in a variety of other practical areas.
SUMMARY
Current data suggest that computed tomographic colonography is a viable colon cancer screening modality in the USA. However, it is not ready for widespread implementation, largely because of lack of standards for training and reading and the fact that the number of skilled readers is limited.
综述目的
计算机断层结肠成像术是一种评估结肠的新型非侵入性方法。本综述的目的是讨论最新数据并明确与计算机断层结肠成像术相关的突出问题。
最新发现
在美国，计算机断层结肠成像术作为一种潜在的原发性结肠癌筛查方法正逐渐兴起。虽然不如结肠镜检查准确，但计算机断层结肠成像术检测大病变的准确率似乎在80%至90%之间。该领域不仅在技术方面，而且在其他各种实际领域都在迅速发展。
总结
目前的数据表明，在美国，计算机断层结肠成像术是一种可行的结肠癌筛查方式。然而，它尚未准备好广泛应用，主要是因为缺乏培训和解读标准，以及熟练的解读人员数量有限。
