目的比较彩超、CT和动态增强MRI诊断子宫内膜癌术前分期的价值。方法收集2012年3月-2015年1月来院就诊的子宫内膜癌疑似病例129例,分别给予彩超、CT和动态增强MRI检查,并与术后病理诊断比较,分析各项检查的临床诊断差异。结果 MRI诊断具有最高的灵敏度、阳性似然比、阴性似然比和诊断正确率,CT诊断次之,彩超诊断最差,差异均有统计学意义(P<0.05);而三项检查诊断特异度均无统计学差异(P>0.05)。结论MRI具有最佳的子宫内膜癌术前分期诊断效果,CT次之,彩超最差,但彩超诊断具有较高的特异度,可用于子宫内膜癌术前的首选检查和大规模筛查。
Objective To compare the value of color Doppler ultrasonography, CT and dynamic contrast-enhanced MRI in the diagnosis of preoperative staging of endometrial cancer. Methods A total of 129 suspected cases of endometrial cancer from March 2012 to January 2015 were enrolled in this study. Color Doppler ultrasonography, computed tomography and dynamic contrast-enhanced MRI were performed respectively. The differences of clinical diagnosis between the two groups were analyzed. . Results The MRI diagnosis had the highest sensitivity, positive likelihood ratio, negative likelihood ratio and diagnostic accuracy, followed by CT and ultrasound, the difference was statistically significant (P <0.05). The three diagnostic tests were specific Degrees were no significant difference (P> 0.05). Conclusion MRI has the best preoperative staging of endometrial cancer diagnosis, CT followed by the worst ultrasonography, but color Doppler ultrasound diagnosis of high specificity, can be used for preoperative screening of endometrial cancer and large-scale screening .
