Computed tomographic (CT) colonography is being implemented increasingly in the USA and Europe, and in many centers it has become the radiological technique of choice for imaging the whole colorectum. Although high diagnostic accuracy has been demonstrated in both screening and symptomatic populations, controversy persists regarding implementation, who should interpret the examination, and its cost effectiveness, particularly in the context of primary colorectal cancer screening. Published research in recent years has demonstrated efficacy in a wide range of patient groups, striking technical improvements, and high levels of patient acceptability. New developments continue in the fields of computer aided detection, digital cleansing, and integration into positron emission tomography. The purpose of this review is to bring the reader up-to-date with the latest developments in CT colonography, in particular, those of the last year.
计算机断层扫描（CT）结肠成像在美国和欧洲的应用越来越广泛，在许多中心，它已成为对整个结肠进行成像的首选放射技术。尽管在筛查人群和有症状人群中都已证明其具有较高的诊断准确性，但在实施、应由谁解读检查结果以及其成本效益方面仍存在争议，尤其是在原发性结直肠癌筛查的背景下。近年来发表的研究表明，CT结肠成像在广泛的患者群体中具有有效性，技术有了显著改进，且患者接受度较高。计算机辅助检测、数字去伪影以及与正电子发射断层扫描整合等领域也在不断有新进展。本综述的目的是让读者了解CT结肠成像的最新发展，特别是过去一年的进展。
