目的 探讨不同MRI检测方法在 评估子宫内膜癌患者深肌层浸润中的临 床诊断价值。方法 对本院收治的65例子 宫内膜癌患者进行MRI扫描，并将T2WI， CE T1WI，DWI等方法诊断深肌层浸润程度 与手术病理比较。结果 65例子宫内膜癌 患者中，病理证实有深肌层浸润者43例， 无深肌层浸润者22例。T2WI与DWI融合图 像的诊断价值最佳，其准确性达93.85%， 敏感性、特异性分别为95.35%和90.91%， 阳性和阴性预测价值也分别为95.35%和 90.91%。结论 T2WI和DWI的融合信号能够 更好地提供子宫内膜癌深肌层浸润的有效 信息。

Objective To explore the diagnostic value of various MRI methods in evaluating deep myometrial invasion in patients with endometrial carcinoma. Methods Sixty-five patients with endometrial carcinoma were recruited for this study. All patients received MRI scan. The T2WI, CE T1WI and DWI images of deep myometrial invasion were compared with histological examination results. Results Among 65 patients with endometrial carcinoma, 43 were confirmed with deep myometrial invasion by histological analysis, and 22 were without deep myometrial invasion. T2WI-DWI fused images showed best diagnostic value with an accuracy of 93.85%,sensitivity and specificity of 95.35% and 90.91%, and positive and negative predictive value of 95.35% and 90.91%. Conclusion The fused images of T2WI and DWI can better generate useful imaging information of deep myometrial invasion in patients with endometrial carcinoma.
