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 investigate the value of magnetic resonance imaging (MRI) in stage Ⅰ, Ⅱ preoperative staging of endometrial carcinoma. Methods Fifty-two patients with endometrial carcinoma confirmed by sectional curettage and pathological examination underwent MRI examination and preoperative staging. The preoperative staging and surgical pathological staging results were compared. Results According to the FIGO 2009 staging criteria, 52 cases of endometrial carcinoma were classified into 31 cases of stage IA, 15 cases of stage IB and 6 cases of stage II. MRI showed a significant correlation with the pathological stage of endometrial cancer (P <0.05). The sensitivity of preoperative MRI was 90.3%, 86.7% and 83.3% in stage ⅠA, stage ⅠB and stage Ⅱ, and the specificity was 90.5%, 89.2% and 100% respectively, the accuracy rates were 90.4%, 82.1% and 98.1% . Conclusion MRI has a high accuracy for preoperative staging of endometrial carcinoma of stage Ⅰ and Ⅱ, which can be used as a routine examination method.
