目的 探讨磁共振成像(MRI)在 子宫内膜癌浸润、淋巴结转移、宫颈间 质受累中的诊断价值。方法 选取74例子 宫内膜癌患者为研究对象,均接受术前 MRI检查和手术病理检查。以术后病理检 查为依据，评估术前MRI对子宫内膜癌 患者肌层浸润深度、淋巴结转移情况、 宫颈间质受累情况的诊断准确性。结果 MRI诊断子宫内膜癌浸润程度的准确性为 89.2%(66/74)，其中鉴别浅肌层浸润的准 确性为90.2%(46/51)，鉴别深肌层浸润的 准确性分别为87.0%(20/23)；诊断有无 淋巴结转移的准确性为79.7%(59/74)； 诊断有无宫颈间质受累的准确性为 95.9%(71/74)。结论 术前MRI检查可在子 宫内膜癌患者肌层浸润鉴别和宫颈间质受 累的诊断评估中发挥积极影响，但在淋巴 结转移的诊断中准确性较低，建议将其作 为辅助手段应用于早期预测筛查中，以节 省治疗时间，提高诊疗效率。

Objective To investigate the diagnostic value of magnetic resonance imaging (MRI) in endometrial cancer invasion, lymph node metastasis and cervical stroma involvement. Methods 74 cases of patients with endometrial cancer were selected as the study objects. All patients underwent preoperative MRI and surgical pathology examination. Based on the postoperative pathological examination, the accuracy rates of preoperative MRI in the diagnosis of the depth of muscular invasion, lymph node metastasis and cervical stroma involvement in patients with endometrial cancer were evaluated. Results The accuracy rate of MRI in the diagnosis of the degree of endometrial cancer invasion was 89.2% (66/74) and of the identification of the superficial muscular invasion was 90.2% (46/51) and of deep muscular invasion was 87.0% (20/23); The accuracy in the diagnosis of lymph node metastasis was 79.7% (59/74) and in the diagnosis of cervical stroma involvement was 95.9% (71/74). Conclusion Preoperative MRI examination plays positive effect the identification of muscular invasion and the diagnosis and evaluation of cervical stroma involvement in patients with endometrial cancer. However, the accuracy rate in the diagnosis of lymph node metastasis is low. It is suggested that it should be applied as a supplementary means in early prediction and screening to save treatment time and improve the efficiency of diagnosis and treatment.
