摘要
目的:分析子宫内膜癌的MRI表现,探讨MRI在子宫内膜癌术前分期中的价值。方法:回顾分析经分段诊刮病理学证实的33例子宫内膜癌MRI征象,对其中29例行手术治疗,将术前MRI分期与术后病理结果对照。结果:子宫内膜癌的表现:子宫增大,子宫内膜弥漫性不规则增厚,T1WI呈低信号,T2WI为相对高信号,有强化,侵犯肌层时,则T2WI上子宫肌层信号增高,结合带中断,显示不清。MRI诊断子宫内膜癌敏感性93.94%,总的准确率72.41%,Ia期子宫内膜癌诊断准确率50%。结论:MRI能多方位显示子宫内膜癌瘤灶及侵犯范围和深度,明显优于其他影像检查方法,但对Ia期病例的诊断仍有待于进一步提高。
Objective： To analyze the features of MRI of endometrial carcinoma and to evaluate the value of MRI in preoperative staging of endometrial carcinoma. Methods： MRI features in 33 cases of endome trial carcioma diagnosed pathologically by diagnostic uterine curettage were retrospectively analyzed. 29 of 33 cases performed operation, in which the staging by MRI was compared with pathologic results. Results： The MRI features of endometrial carcinoma included enlarged uterus, diffuse and irregular thickening in endometrium, low signal on T1 W1 and relative high signal on T2 W1, Presence of enhancement, increasing signal on T2W1 and blurred and interrupted junction zone when muscalar layer was involved. The sensitivity of MRI was 93.94 % in diagnosing endometrial carcinoma, the total accurate rate was 72.41% and the accurate rate in diagnosing endometrial carcinoma in stase Ia was 50 %. Conclusion. MRI can clearly display the extent and depth of endometrial carcinoma from various directions MRI is obviously superior to other imaging examinations The application of MRI in diagnosis in disease in stage Ia should be fur therly improved.
