摘　　要：目的探讨MRI动态增强扫描对判断Ⅰ期子宫内膜癌肌层浸润深度的价值。方法回顾分析23例经手术病理证实为Ⅰ期子宫内膜癌的T_1WI、T_2WI平扫及动态增强MRI表现,根据FIGO分期原则进行MR分期,并与病理结果对照。结果 23例Ⅰ期子宫内膜癌T_2WI结合带模糊或不清17例,结合带中断5例,1例结合带未显示。动态增强内膜下强化带完整1例,强化带中断17例,强化带未显示、肌层内表面不规则5例。与病理结果对照,动态增强判断肌层浸润深度的诊断符合率为87%。结论动态增强MRI对Ⅰ期子宫内膜癌的诊断和分期具有较高的价值,应为术前常规检查。Objective To assess the value of dynamic contrast-enhanced（DCE）MRI in detecting myometrial invasion of stage I endometrial carcinoma.Methods The pre-and post-contrast MRI of 23 patients with stage I endometrial carcinoma confirmed by surgery was retrospectively analyzed and compared with pathology.Results Of 23 tumors,subendometrial enhancement on DCE-MRI was breached（17）,irregular（5）,or intact（1）.The accuracy of DCE-MRI was 87%for diagnosing stage I endometrial carcinoma.Conclusion DCE-MRI is valuable in depicting the depth of myometrial invasion of stage I endometrial carcinoma.
