目的:探讨常规超声与超声弹性成像在甲状腺结节诊断中的不同应用价值。方法:选取石柱县人民医院2012年10月至2014年10月收治的甲状腺结节患者86例(104个结节),分别行常规超声、弹性成像检查,比较两种检查诊断方式的灵敏度、特异性、阳性与阴性预测值、诊断准确率。结果:经手术病理证实,104个结节良性78个、恶性26个;常规超声诊断准确率为68.27%;超声弹性成像诊断准确率为91.34%,明显高于常规超声诊断准确率,差异具有统计学意义(P<0.05)。结论:在甲状腺结节的临床诊断上,超声弹性成像的应用价值明显高于常规超声。
Objective: To investigate the different value of routine ultrasound and elastography in the diagnosis of thyroid nodules. Methods: 86 cases (104 nodules) of thyroid nodules who were treated in Shizhu People’s Hospital from October 2012 to October 2014 were selected and examined by routine ultrasound and elastography. The sensitivity and specificity of the two diagnostic methods were compared Sex, positive and negative predictive value, diagnostic accuracy. Results: Surgical pathology confirmed that there were 78 benign nodules and 26 malignant lesions in 104 nodules. The accuracy rate of conventional ultrasonic diagnosis was 68.27%. The diagnostic accuracy of ultrasonic elastography was 91.34%, which was significantly higher than that of routine ultrasonic diagnosis. The difference was statistically significant Significance (P <0.05). Conclusion: The clinical value of ultrasound elastography in the diagnosis of thyroid nodules is significantly higher than that of conventional ultrasound.
