To update quality standards for CT colonography based on consensus among opinion leaders within the European Society of Gastrointestinal and Abdominal Radiology (ESGAR).
A multinational European panel of nine members of the ESGAR CT colonography Working Group (representing six EU countries) used a modified Delphi process to rate their level of agreement on a variety of statements pertaining to the acquisition, interpretation and implementation of CT colonography. Four Delphi rounds were conducted, each at 2 months interval.
The panel elaborated 86 statements. In the final round the panelists achieved complete consensus in 71 of 86 statements (82 %). Categories including the highest proportion of statements with excellent Cronbach's internal reliability were colon distension, scan parameters, use of intravenous contrast agents, general guidelines on patient preparation, role of CAD and lesion measurement. Lower internal reliability was achieved for the use of a rectal tube, spasmolytics, decubitus positioning and number of CT data acquisitions, faecal tagging, 2D vs. 3D reading, and reporting.
The recommendations of the consensus should be useful for both the radiologist who is starting a CTC service and for those who have already implemented the technique but whose practice may need updating.
根据欧洲胃肠道和腹部放射学会（ESGAR）内意见领袖之间的共识，更新 CT 结肠成像质量标准。
一个由 9 名 ESGAR CT 结肠成像工作组成员组成的多国籍欧洲小组（代表 6 个欧盟国家）使用改良 Delphi 法对与 CT 结肠成像的采集、解释和实施相关的各种陈述进行了评价，并就其达成一致意见的程度进行了评分。共进行了四轮 Delphi 调查，每轮间隔 2 个月。
该小组阐述了 86 条陈述。在最后一轮中，小组成员在 86 条陈述中的 71 条（82%）上达成了完全一致。包括结肠扩张、扫描参数、静脉造影剂使用、患者准备一般指南、CAD 和病变测量作用等类别的陈述，具有最高比例的优秀 Cronbach's 内部可靠性。直肠管、痉挛剂、卧位定位和 CT 数据采集次数、粪便标记、2D 与 3D 阅读以及报告的使用等类别的内部可靠性较低。
共识的建议对于刚开始提供 CTC 服务的放射科医生和已经实施该技术但可能需要更新实践的医生都将非常有用。
