To determine the incidence and clinical relevance of extra-intestinal incidental findings (IF) in a cohort of patients with proven or suspected Crohn disease (CD) examined with magnetic resonance enterography (MR-E) in a single University Centre.
Between January 2018 and June 2019, 182 patients with proven or suspected CD with a planned first MR-E examination, were retrospectively included in this study. Incidental findings were considered as any abnormality identified in the absence of previous clinically suspected or known disease. IF were categorized as unremarkable, benign or potentially relevant findings requiring further imaging or specific treatment.
Of the 182 revised MR-E, extra-intestinal IF were recorded in 70 cases (38.5%); 35 (50%) incidental lesions were recognized as non-significant, 24 (34%) as benign and 11 (16%) as clinically relevant. Moreover, there was a positive correlation between IF and patients' age (p < 0.0001).
In our experience, a high number of IF (38.5%) was found, with a prevalence that increases with patients' age. Clinically relevant findings were found in 16% of MR-E. This means that MR-E is a useful tool to detect IF, therefore, the presence of a radiologist during the image acquisition is crucial in adding sequences to the examination.
在单一大学中心，对经磁共振肠成像（MR-E）检查确诊或疑似克罗恩病（CD）的患者队列中，确定肠道外偶然发现（IF）的发生率及其临床相关性。
2018 年 1 月至 2019 年 6 月，对计划进行首次 MR-E 检查的 182 例确诊或疑似 CD 患者进行回顾性分析。偶然发现被定义为在没有先前临床怀疑或已知疾病的情况下发现的任何异常。IF 被分为无明显异常、良性或可能具有相关性，需要进一步影像学或特定治疗的发现。
在 182 例修订后的 MR-E 中，70 例（38.5%）记录到肠道外 IF；35 例（50%）偶然病变被认为无明显意义，24 例（34%）为良性，11 例（16%）为临床相关。此外，IF 与患者年龄之间存在正相关（p<0.0001）。
根据我们的经验，发现了大量 IF（38.5%），其发生率随患者年龄增加而增加。MR-E 中发现了 16%的具有临床相关性的发现。这意味着 MR-E 是一种检测 IF 的有用工具，因此，在图像采集过程中，放射科医生的存在对于添加检查序列至关重要。
