核磁共振在术前诊断子宫内膜癌肌层及宫颈浸润中的意义

目的：探讨MRI检查对子宫内膜癌肌层浸润及宫颈浸润的术前诊断及分期价值。方法：回顾性分析55例子宫内膜癌患者临床资料，分析子宫内膜癌术前盆腔的核磁共振图像特点，判断分期并与手术病理结果相比较。结果：55例子宫内膜癌，MRI均检出。46例MRI检查能够清楚显示瘤灶的形态及大小，术前做出正确分期；MRI分期与病理分期比较，不符合9例，其中过高分期4例，Ⅰb期MRI诊断为ⅠC期；过低分期5例，ma期MRI诊断为Ⅰc期，Ⅲc期MRI诊断Ⅲa期。结论：术前盆腔MRI并增强检查可作为子宫内膜癌患者必须检查项目之一，其为术前诊断子宫内膜癌子宫肌层浸润深度、宫颈浸润和制定治疗方案提供可靠依据。

Nuclear magnetic resonance in preoperative diagnosis for muscular and cervical infiltration of endometrial carcinoma

Objective:To explore the value of magnetic resonance imaging(MRI) in preoperative diagnosis and staging for muscular and cervical infiltration of endometrial carcinoma.Methods:Clinic data of 55 cases with endometrial carcinoma was retrospectively analyzed.The preoperative MRI images of pelvic,stages were reviewed and compared with pathological results.Results:All cases were diagnosed as endometrial cancer via MRI.46 cases reviewed and showed clear tumor lesion,and were staged accurately before operation.9 cases had different MRI staging from pathological results,including 4 cases being judged as Ⅰb stage but was diagnosed asⅠc stage by MRI,and 5 cases being judged as Ⅲa stage but was diagnosed asⅠc stage by MRI,and Ⅲc stage but was diagnosed as Ⅲa stage.Conclusion:Preoperative pelvic MRI and its strengthening examination is necessary for endometrial cancer,and can provide reliable evidence for diagnosis of depth of muscular infiltration,cervical infiltration and arrangement for the treatment.
