目的分析在子宫内膜癌诊断、术前分期以及临床治疗中应用MRI的价值。方法抽取2015-05-2016-05在我院诊治的子宫内膜癌患者50例,全部患者都应用MRI进行诊断,并将诊断结果和病理诊断的结果进行对比。结果在50例子宫内膜癌的患者中,在子宫肌层的浸犯深度判断方面,Ⅰa期MRI高估了1例;Ⅰb期患者高估2例、低估2例;Ⅰc期患者低估2例;Ⅱ期患者高估2例、低估1例;Ⅲ期、Ⅳ期和病理的分期相符,通过MRI分期的准确率为80.00%。结论在子宫内膜癌患者诊断中应用MRI,可以准确分期,清楚判断宫颈浸润的深度与子宫内膜癌的肌层,具有应用的价值。 Objective To analyze the value of MRI in the diagnosis, preoperative staging and clinical treatment of endometrial carcinoma. Methods Fifty patients with endometrial cancer diagnosed and treated in our hospital from May 2015 to May 2016 were retrospectively reviewed. All patients were diagnosed by MRI and the diagnostic results were compared with the results of pathological diagnosis. Results In 50 cases of endometrial cancer, Ia MRI was overestimated in 1 case in terms of depth of myometrial invasion, 2 cases were overestimated in stage Ⅰb, 2 cases underestimated, and 2 cases were underestimated in stage Ⅰc ; 2 patients overestimated in 2 cases, underestimated in 1 case; Ⅲ, Ⅳ phase consistent with the pathological stage, the accuracy of MRI staging by 80.00%. Conclusion The diagnosis of endometrial cancer patients with MRI, accurate staging, a clear judgment of the depth of cervical invasion and endometrial cancer muscle, with the application value.
