摘　　要：目的:探讨MRI在子宫内膜癌的诊断、分期中的作用。方法:回顾性研究273例经术后病理检查明确诊断的子宫内膜癌患者,根据其术前MRI表现,以FIGO2009新分期方法结合病理分期结果进行评估。结果:273例患者中Ia期136例,Ib期46例,II期51例,IIIa期8例,IIIb期7例,IIIc1期8例,IIIc2期4例,IVa期6例,IVb期7例,MRI对子宫内膜癌分期正确率为93.4%,与病理分期比较无显著统计学差异(P>0.05)。结论:MRI对子宫内膜癌的诊断及分期具有较高准确性,在临床治疗方式及预后评估中具有重要意义。Objective： To investigate the value of magnetic resonance imaging（ MRI） features in preoperative of endometrial cancer. Methods： To analyze 273 patients with pathologically confirmed endometrial carcinoma,according to FIGO2009 staging criteria of endometrial carcinoma,the MRI features of the tumor were evaluated by myometrial invasion and cervical involvement. Results： In 273 cases,there were 136 cases of Iastage,46 cases of Ibstage,51 cases of II stage,8 cases of IIIastage,7 cases of IIIbstage,8 cases of IIIc1 stage,4 cases of IIIc2 stage,6 cases of IIIc2 stage,7 cases of IVbstage. The accuracy of preoperative MRI- based staging of endometrial carcinoma was 93. 4%,there was no significant difference from the results of postoperative FIGO 2009 staging and pathological examination（ P 0. 05）. Conclusion： MRI has a high accuracy in the diagnosis,evaluation of myometrial and cervical invasion depth,and preoperative staging of endometrial carcinoma,and serves as an important modality in assisting clinical decisions on the optimal therapeutic protocols and in prognostic estimation.
