目的 探讨磁共振成像(MRI)在 子宫内膜癌术前诊断中的价值。方法 选 取2015年1月至2017年9月在我院治疗的 124例子宫内膜癌患者，比较术前MRI检 查结果与病理结果。结果 术前MRI临床 分期与病理分期结果一致性Kappa值为 0.724，P＜0.05，一致性较好；术前MRI 评价肌层浸润与术后病理结果一致性 Kappa值为0.741，P＜0.05，一致性较 好；术前MRI评价浅肌层浸润灵敏度、 特异度、阳性预测值、阴性预测值和准 确度分别为86.44%、87.69%、86.44%、 87.69%和87.10%；术前MRI评价盆腹腔淋 巴结转移与术后病理结果一致性Kappa值 为0.275，P＜0.05，一致性较差，术前 MRI评价盆腹腔淋巴结转移的灵敏度、特 异度、阳性预测值、阴性预测值和准确度 分别为22.22%、98.26%、50.00%、94.17% 和92.74%。结论 MRI术前诊断子宫内膜癌 临床分期、判断肌层浸润情况有较好的应 用价值，但判断盆腹腔淋巴结转移的应用 价值不高。

Objective To explore the value of magnetic resonance imaging (MRI) in the diagnosis of endometrial carcinoma before operation. Methods 124 cases of endometrial cancer were treated in our hospital from January 2015 to September 2017, and the results of preoperative MRI examination and postoperative pathological results were compared. Results The Kappa value of preoperative MRI clinical staging and postoperative pathological staging was 0.724, P<0.05, and the consistency was better. Preoperative MRI evaluation of myometrium infiltration and postoperative pathological results showed that the Kappa value was 0.741, P<0.05, and the consistency was better. Preoperative MRI evaluation of superficial muscle layer invasion showed that the sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 86.44%, 87.69%, 86.44%, 87.69% and 87.10%, respectively. Preoperative MRI evaluation of pelvic and abdominal lymph node metastasis and postoperative pathological results showed that Kappa value was 0.275, P<0.05, the consistency was poor,the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of preoperative MRI for pelvic and abdominal lymph node metastasis were 22.22%, 98.26%, 50%, 94.17% and 92.74%, respectively. Conclusion MRI preoperative diagnosis of endometrial carcinoma clinical staging and evaluation of myometrium infiltration has good application value, However, it has low application value to judge pelvic and abdominal lymph node metastasis.
