MRI术前评估子宫内膜癌分期及肌层浸润的意义

摘要

目的：评价磁共振成像（MRI）在子宫内膜癌术前分期及肌层浸润深度判定中的作用。方法：56例子宫内膜癌患者术前均行常规和造影剂增强 MRI 扫描，术前评估分期和肌层浸润深度并与术后病理结果比较。结果： MRI检查术前分期诊断准确率为82．1％（46／56），一致性检验（Kappa ＝0．771，P ＜0．001）。结论： MRI对子宫内膜癌术前评估肌层浸润深度和检测肿瘤扩展分期具有灵敏度高、特异性好的特点，可作为子宫内膜癌术前评估的常规检查。%Objective To assess the effect of magnetic resonance imaging (MRI) on preoperative staging of endometrial carcinoma and depth of myometrial invasion. Methods Fifty-six patients with endometrial carcinoma were underwent conventional and contrast-enhanced MR scan. The results of pathology , MRI examinations of preoperative staging and depth of myometrial invasion were assessed and compared. Results The accurate rate of MRI diagnosis in preoperative staging diagnosis was 82.1% (46/56) and the consistency check as Kappa was 0.771 (P < 0.001). Conclusions MRI may be a good diagnostic tool with high sensitivity and specificity for assessing myometrial invasion and detecting tumour extension and should be considered as a routine part of the preoperative assessment in all patients with endometrial carcinoma.
