To develop guidelines describing a standardised approach regarding the acquisition, interpretation and reporting of magnetic resonance imaging (MRI) for clinical staging and restaging of rectal cancer.
A consensus meeting of 14 abdominal imaging experts from the European Society of Gastrointestinal and Abdominal Radiology (ESGAR) was conducted following the RAND-UCLA Appropriateness Method. Two independent (non-voting) chairs facilitated the meeting. Two hundred and thirty-six items were scored by participants for appropriateness and classified subsequently as appropriate or inappropriate (defined by ≥ 80 % consensus) or uncertain (defined by < 80 % consensus). Items not reaching 80 % consensus were noted.
Consensus was reached for 88 % of items: recommendations regarding hardware, patient preparation, imaging sequences, angulation, criteria for MRI assessment and MRI reporting were constructed from these.
These expert consensus recommendations can be used as clinical guidelines for primary staging and restaging of rectal cancer using MRI.
• These guidelines recommend standardised imaging for staging and restaging of rectal cancer. • The guidelines were constructed through consensus amongst 14 abdominal imaging experts. • Consensus was reached by in 88 % of 236 items discussed.
制定指南，描述一种标准化的方法，用于采集、解释和报告磁共振成像（MRI）在直肠癌临床分期和再分期中的应用。
采用 RAND-UCLA 适宜性方法，对来自欧洲胃肠道和腹部放射学会（ESGAR）的 14 名腹部影像学专家进行了共识会议。两名独立（无表决权）主席主持了会议。236 项内容由与会者进行了适宜性评分，并随后归类为适宜（定义为≥80%的共识）或不适宜（定义为<80%的共识）或不确定（定义为<80%的共识）。未达到 80%共识的项目将被记录。
达成了 88%的项目的共识：从这些项目中构建了有关硬件、患者准备、成像序列、角度、MRI 评估标准和 MRI 报告的建议。
这些专家共识建议可作为使用 MRI 进行直肠癌初始分期和再分期的临床指南。
这些指南建议对直肠癌进行标准化的影像学分期和再分期。
该指南是通过 14 名腹部影像学专家的共识构建的。
在讨论的 236 项内容中，有 88%达成了共识。
