This expert consensus document represents an initiative by the European Neuroendocrine Tumor Society (ENETS) to provide guidance for synoptic reporting of radiological examinations critical to the diagnosis, grading, staging and treatment of neuroendocrine neoplasms (NENs). Template drafts for initial tumor staging and follow-up by computed tomography (CT) and magnetic resonance imaging (MRI) were established, based on existing institutional and organisational reporting templates relevant for NEN imaging, and applying the RadLex lexicon of radiological information (Radiological Society of North America), for consistency regarding the radiological terms. During the ENETS Scientific Advisory Board meeting 2018, the template drafts were subject to iterative interdisciplinary discussions among experts in imaging, surgery, gastroenterology, oncology and pathology. Members of the imaging group stated a strong preference for a combination of limited and standardised options by way of drop-down menus. Separate templates were produced for the initial work-up and for follow-up, respectively. To provide a detailed description of the radiological findings of the primary tumor and its local extension and spread, different templates were developed for bronchial, pancreatic and gastrointestinal NENs for CT and MRI, respectively. Each template was structured in 10 sections: clinical details, comparative imaging modality, acquisition technique, primary tumor findings, regional lymph node metastases, distant metastases, TNM classification, reference lesions according to RECIST 1.1, additional findings and conclusion. Two templates were developed for follow-up, for CT and MRI, respectively, and were specifically focused on assessment of therapy response. These included a qualitative response assessment, such as decrease of vascularisation and presence of necrosis, and a quantitative assessment according to RECIST 1.1 and the modified RECIST (mRECIST) for assessing tumor response following transarterial chemoembolisation.

用于神经内分泌肿瘤放射成像的 ENETS 标准化（概要）报告

该专家共识文件代表了欧洲神经内分泌肿瘤协会 (ENETS) 的一项倡议，旨在为对神经内分泌肿瘤 (NEN) 的诊断、分级、分期和治疗至关重要的放射检查的概要报告提供指导。基于现有的与 NEN 成像相关的机构和组织报告模板，并应用 RadLex 放射学信息词典（Radiological Society北美），以保持放射学术语的一致性。在 2018 年 ENETS 科学顾问委员会会议期间，模板草案接受了影像、外科、胃肠病学、肿瘤学和病理学。成像小组的成员表示强烈偏好通过下拉菜单将有限和标准化选项结合起来。分别为初始工作和后续工作制作了单独的模板。为了详细描述原发肿瘤的放射学发现及其局部扩展和扩散，分别为 CT 和 MRI 的支气管、胰腺和胃肠道 NEN 开发了不同的模板。每个模板分为 10 个部分：临床细节、比较成像方式、采集技术、原发肿瘤发现、区域淋巴结转移、远处转移、TNM 分类、根据 RECIST 1.1 的参考病变、附加发现和结论。为随访开发了两个模板，分别用于 CT 和 MRI，并特别关注治疗反应的评估。其中包括定性反应评估，例如血管化减少和坏死的存在，以及根据 RECIST 1.1 和改进的 RECIST (mRECIST) 进行的定量评估，用于评估经动脉化疗栓塞后的肿瘤反应。
