Computed tomography colonography has evolved over the past 2 decades to become the primary alternative to optical colonoscopy for detection of colonic neoplasia. With good technique in performance and reporting, accuracy is comparable to optical colonoscopy for cancers and larger polyps. This article discusses the current components of a high-quality examination including contemporary methods of bowel preparation and distension. Also described is the main trial data that have validated the examination. Finally, the use of the technique for nonneoplastic colonic pathology is discussed, and future directions are described including magnetic resonance colonography and wireless capsule colonic imaging.
在过去20年中，计算机断层扫描结肠成像技术不断发展，已成为用于检测结肠肿瘤的光学结肠镜检查的主要替代方法。凭借良好的操作和报告技术，其对癌症和较大息肉的检测准确性与光学结肠镜检查相当。本文讨论了高质量检查的当前组成部分，包括当代的肠道准备和扩张方法。还介绍了验证该检查的主要试验数据。最后，讨论了该技术在非肿瘤性结肠病变中的应用，并描述了未来的发展方向，包括磁共振结肠成像和无线胶囊结肠成像。
