回顾性分析子宫内膜癌的磁共振（MRI）表现和手术病理结果，探讨MRI诊断和分期的价值。材料和方法：18例子宫内膜癌诊断和分期均经手术和病理检查。术前MRI检查采取冠状面和矢状面的T1WI和T2WI成像，双盲法MRI阅片，子宫内膜癌MRI分期基本按FIGO分期原则。结果：病灶区在T1WI像上为等信号（不伴出血），T2WI呈现5种表现。MRI分期准确率达83．8％，分辨工期的准确率达90．9％。结论：子宫内膜癌MRI表现多样化，有44．4％病例表现不典型。MRI对子宫内膜癌（尤其对占多数的Ⅰ期病例）的分期具有很高的价值。
The MRI findings and pathological findings of endometrial carcinoma were analyzed retrospectively to investigate the value of MRI diagnosis and staging. Materials and Methods: 18 cases of endometrial cancer diagnosis and staging by surgery and pathological examination. Preoperative MRI to take coronal and sagittal T1WI and T2WI imaging, double-blind MRI reading, MRI staging of endometrial cancer according to FIGO staging principle. Results: The lesion area was equal in T1WI image (without hemorrhage), and T2WI showed 5 kinds of manifestations. MRI staging accuracy rate of 83.8%, resolution accuracy of 90.9%. Conclusion: The MRI findings of endometrial carcinoma are diversified, with 44.4% of cases showing atypical cases. MRI is of great value in the staging of endometrial cancer, especially in the predominantly stage I disease.
