超声与CT在多发性甲状腺结节诊断中的价值对比

Comparison of Value of Ultrasonography and CT in Diagnosis of Multiple Nodules in Throid

目的:探讨彩色多普勒超声与CT在多发性甲状腺结节诊断中的差异。方法:回顾性分析我院2011年3月-2012年6月收治的多发性甲状腺结节患者78例的临床资料,并将所有超声、CT结果与术后病理进行比较分析。结果:应用超声、CT和两种方法联用的准确率分别为83.33%、75.64%、91.03%,灵敏性分别为67.95%、51.28%、83.33%,特异性分别为85.89%、80.77%、92.31%。超声、CT联合诊断在准确性、误诊率、漏诊率、敏感性和特异性均显著好于任意方法单独使用(P<0.05),超声诊断结果虽略好于CT,但不存在统计学差异(P>0.05)。结论:超声和CT作为多发性甲状腺结节的术前辅助诊断手段各具特色,两种方法联合应用,可达到互补,提高诊断准确率和特异性的效果。

Objective： To investigate the difference between ultrasonography and CT in diagnosis of multiple nodules in throid. Methods： The clinical data of 78 patients with multiple nodules in throid of our hospital from March 2011 to June 2012 were retrospective analyzed, and the results of uhrasonography and CT were compared with pathological results. Results： The accuracy of ultrasonography, CT and combination of two methods were 83.33%, 75.64% and 91.03%, the sensitivity were 67.95%, 51.28% and 83.33%, and the specificity were 85.89%, 80.77% and 92.31%. The combination of two methods had a significantly higher than any other methods used alone in accuracy, sensitivity and specificity （P〈0.05）, and there was no difference between uhrasonography and CT（P〉0.05）. Conclusion： Uhrasonography and CT has different characters in diagnosis, its combination can achieve the effect of complementary, and also improve the accuracy and specificity.
