目的对已发表的CT结肠成像和光学结肠镜(OC)检测结直肠癌的敏感性评估研究行系统回顾及荟萃分析。材料与方法分析遵循系统回顾和荟萃分析推荐的优先报告条目。原始数据来源为PubMed上1994年—2009年间的精细搜索结果。CT结肠成像检测结直肠癌的诊断性研究,须有预先确定的纳入和排除标准,尤其需结肠镜和病理学确诊。使
OBJECTIVE: To systematically review and meta-analysis of the published studies evaluating the sensitivity of CT colonography and optical colonoscopy for the detection of colorectal cancer. Materials and Methods Analysis Follow the recommended priority report entries for systematic review and meta-analysis. The original source for the data was PubMed’s 1994-09 search results. CT colonography for the diagnosis of colorectal cancer diagnosis, there must be a predetermined inclusion and exclusion criteria, especially colonoscopy and pathology confirmed. Make
