磁共振成像在Ⅰ、Ⅱ期子宫内膜癌术前分期中的应用分析

Application analysis of magnetic resonance imaging in preoperative staging of stage I and II endometrial carcinoma

目的探讨磁共振成像(magnetic resonance imaging,MRI)在Ⅰ、Ⅱ期子宫内膜癌术前分期中的价值。方法对52例经分段诊刮及病理检查证实的子宫内膜癌患者行MRI检查,并进行术前分期,将术前分期与手术病理分期结果进行比较。结果 52例子宫内膜癌按照FIGO 2009分期标准,MRI判断为ⅠA期31例,ⅠB期15例,Ⅱ期6例,MRI对子宫内膜癌分期与病理分期显著相关(P<0.05)。术前MRI分期ⅠA期、ⅠB期、Ⅱ期敏感性分别为90.3%、86.7%、83.3%,特异性分别为90.5%、89.2%、100%,准确率分别为90.4%,82.1%、98.1%。结论 MRI对Ⅰ、Ⅱ期子宫内膜癌术前分期准确性高,可以作为常规检查手段。

Objective To discuss the value of magnetic resonance imaging（MRI） in preoperative staging of stage Ⅰ and Ⅱ endometrial carcinoma. Methods 52 patients with endometrial carcinoma confirmed by curettage and pathological examination were taken MR examination, and preoperative staging was performed, preoperative staging and surgical pathological staging results were compared. Results According to the FIGO 2009 criteria, in the 52 cases with endometrial carcinoma,31 cases were diagnosed as stage Ⅰ A,15 cases as stage Ⅰ B and 6 cases as stage Ⅱ by MRI, MRI in preoperative staging of endometrial carcinoma and pathological staging had significantly relationship（P 〈0. 05）. The sensitivity of MRI preoperative stage of Ⅰ A, ⅠB, Ⅱ were 90. 3% , 86. 7% , 83.3% , specificity were 90. 5%, 89.2%, 100% and accuracy were 90. 4%, 82. 1%, 98. 1%. Conclusion MRI is an accurate method in preoperative staging for stage Ⅰ and Ⅱ endometrial carcinoma, which can be used as a routine examination.
