目的：探讨妇科盆腔恶性肿瘤放疗后所导致的放射线肠炎（ RE）磁共振成像（ MRI）特征。方法选取武警医院放射科进行MRI检查，并经内镜活检或手术证实的RE患者50例，回顾性分析其临床资料和MRI特征。结果 RE主要发生在放疗后4～8月；发生部位在小肠46．0％，直肠22．0％，结肠32．0％；MRI主要特征表现为肠壁明显增厚，T2W、DWI上肠壁表现为环状分层信号，呈靶征样分层改变；CT检测发现163处病变，MRI发现171处，MRI和CT检出病变肠段的符合率为91．8％（χ2＝0．375，P＞0．05）。结论妇科盆腔恶性肿瘤放疗后的放射性肠炎具有一定的MRI特征，具有临床诊断价值。
目的：探討婦科盆腔噁性腫瘤放療後所導緻的放射線腸炎（ RE）磁共振成像（ MRI）特徵。方法選取武警醫院放射科進行MRI檢查，併經內鏡活檢或手術證實的RE患者50例，迴顧性分析其臨床資料和MRI特徵。結果 RE主要髮生在放療後4～8月；髮生部位在小腸46．0％，直腸22．0％，結腸32．0％；MRI主要特徵錶現為腸壁明顯增厚，T2W、DWI上腸壁錶現為環狀分層信號，呈靶徵樣分層改變；CT檢測髮現163處病變，MRI髮現171處，MRI和CT檢齣病變腸段的符閤率為91．8％（χ2＝0．375，P＞0．05）。結論婦科盆腔噁性腫瘤放療後的放射性腸炎具有一定的MRI特徵，具有臨床診斷價值。

Objective To investigate the MRI characteristics of radiation enteritis ( RE) caused by gynecologic pelvic malignant tumor after radiotherapy .Methods Fifty patients with RE performed MRI examination , and they were confirmed by endoscopic biopsy or surgery . Retrospective analysis was conducted on clinical data and MRI characteristics .Results RE mainly happened in 4 -8 month after radiotherapy.The location of RE was in small intestine (46.0%), rectum (22.0%) and colon (32.0%).The MRI features of RE was thicken bowel wall, and annular layered signal was found in T2W and DWI intestinal wall with target sign layered change .By CT examination 163 lesions were found, and 171 lesions were found by MRI.MRI and CT detection coincidence rate was 91.8% (χ2 =0.375,P>0.05).Conclusion The RE of gynecology pelvic malignant tumor after radiotherapy has certain MRI characteristics with clinical diagnostic value .
