目的:对超声和CT在甲状腺多发结节中良恶性结节鉴别诊断的临床价值进行分析和探讨。方法:选取我院2010年8月~2013年8月收治的甲状腺多发结节患者240例,术前分别使用CT、超声及CT-超声结合对患者的甲状腺结节进行诊断,患者的检查结果按检查方式分为CT组、超声组和联合组,根据检查结果对这三种诊断方式的符合率、敏感性、特异性进行比较和分析。结果:CT检查与超声检查的特异性、敏感性和符合率无明显差异(P>0.05),CT检查的特异性、敏感性和符合率均显著低于CT-超声联合检查(P<0.05),超声检查的特异性与敏感性与CT-超声联合检查的结果无显著差异(P>0.05),但符合率明显低于CT-超声综合判断(P<0.05)。结论:超声与增强CT结合可提高甲状腺多发结节中良恶性结节的判断的准确性。
Objective: To analyze and discuss the clinical value of differential diagnosis of benign and malignant nodules in multiple thyroid nodules by ultrasound and CT. Methods: A total of 240 thyroid nodules were selected from August 2010 to August 2013 in our hospital. Thyroid nodules were diagnosed by CT, ultrasonography and CT-ultrasonography before operation. The examination methods were divided into CT group, ultrasound group and combination group. According to the examination results, the coincidence rate, sensitivity and specificity of the three diagnostic methods were compared and analyzed. Results: The specificity, sensitivity and coincidence rate of CT examination and ultrasonography had no significant difference (P> 0.05). The specificity, sensitivity and coincidence rate of CT examination were significantly lower than those of CT-ultrasound examination (P0.05) The specificity and sensitivity of ultrasound examination were not significantly different from those of CT-ultrasound examination (P> 0.05), but the coincidence rate was significantly lower than that of CT-ultrasound (P <0.05). Conclusion: The combination of ultrasound and enhanced CT can improve the accuracy of benign and malignant nodules in multiple thyroid nodules.
