37例子宫内膜癌MRI表现及分期[摘要] 目的 分析子宫内膜癌MRI的表现，探讨MRI对子宫内膜癌诊断及分期价值。方法 回顾性分析37例经病理证实的子宫内膜癌患者的MRI表现、诊断及分期。结果 子宫内膜癌MRI的典型表现为子宫增大，内膜不规则增厚，在T2WI肿瘤组常呈略高及低信号，与肌层形成较好对比，能较准确判断肿瘤大小及侵犯范围，增强扫描肿瘤信号低于肌层，DWI肿瘤呈高信号。结论 MRI对子宫内膜癌的早期诊断、肿瘤分期及病变范围的判断有较高价值，对临床制订治疗方案及术后评估具有重要指导意义。 [关键词] 子宫内膜癌；磁共振成像；肿瘤分期 [中图分类号] R445.2[文献标识码] B [文章编号] 1673-9701（2011）27-118-02 The Staging and Display on the MRI of Endometrial Carcinoma XIANG Shifeng ZHANG ShupingWANG WeizhiXIANG JianyuWANG TingyuQIU Qiande Department of Radiology，Wenzhou City the Third People’s Hospital，Zhejiang Province，Wenzhou 325000，China [Abstract] Objective To analyze the features of MRI of endometrial carcinoma，and to evaluate the application of MRI in its diagnosis and preoperative stsging. Methods Thirty-seven cases MRI display diagnosis and staging of endometrial carcinoma which confirmed by pathology were retrospective analyzed，and the diagnostic results of MRI were compared with the pathological. Results The MRI features of endometrial carcinoma included enlarged uterus，diffuse and irregular thickening in endometrial，T2WI tumor groups often were relative high and low signal，and good contrast to muscle，which could determine its size and scope of violations interrupt junction zone more accurately. The signal of Endometrial carcinoma was lower by contrast enhancement，while the DWI was higher. Conclusion The MRI on endometrial carcinoma for early diagnosis，staging and judgment has the higher value for the disease range，and has important guiding significance in treatment protocols andpostoperative evaluation.
