目的：研究磁共振弥散加权成像（DWI）和动态增强（DCE）成像在子宫内膜癌分期中的价值。方法选取子宫内膜癌患者200例，术前均给予磁共振 DWI 和磁共振 DCE 检查，比较两种检查方法对子宫内膜癌总体分期、肌层浸润的诊断价值。结果磁共振 DWI 评估肌层浸润整体准确率为91．5％（183／200），显著高于磁共振 DCE 的77．5％（155／200），差异有统计学意义（χ2＝11．231，P ＜0．05）；磁共振 DWI 浅肌层和深肌层浸润准确率、灵敏度以及阳性预测值均显著高于磁共振 DCE，两者差异均有统计学意义（χ2＝9.283、8．231、9．021、8．927、8．142、9．405，均 P ＜0．05）；与病理结果比较，磁共振 DWI 的 Kappa 值为0．807，磁共振DCE 的 Kappa 值为0．587。结论磁共振 DWI 与磁共振 DCE 比较，对子宫内膜癌肌层浸润的准确率和灵敏度均较高。

Objective To study the value of magnetic resonance diffusion weighted imaging (DWI)and dynamic enhanced imaging (DCE)in endometrial carcinoma staging.Methods 200 cases with endometrial carcinoma were selected,DWI and DCE were given before operation.The diagnostic value of two kinds of examination methods for the diagnosis of endometrial carcinoma in general and basic level was compared.Results The overall accuracy of muscle invasion of magnetic resonance DWI was 91.5%(183 /200),which was significantly higher than 77.5%(155 /200)of magnetic resonance DCE,the difference was statistically significant (χ2 =11.231,P <0.05 ).The accuracy,sensitivity and positive predictive value of the magnetic resonance DWI superficial and deep muscular layer were significantly higher than those of the magnetic resonance DCE (χ2 =9.283,8.231,9.021,8.927,8.142, 9.405,all P <0.05).Compared with pathological results,Kappa value of magnetic resonance DWI was 0.807,Kappa value of magnetic resonance DCE was 0.587.Conclusion Magnetic resonance DWI compared with magnetic reso-nance DCE,the accuracy and sensitivity of the infiltration of endometrial carcinoma was higher.
