研究超声弹性成像在甲状腺结节良恶性诊断中的价值

Diagnostic Value of Ultrasound Elastography in Benign and Malignant Thyroid Nodules

目的讨论超声弹性成像在甲状腺结节良恶性诊断中的价值。方法选择2018年1—12月我院收治甲状腺结节患者86例,共128个结节,在常规超声检查的基础上,所有患者均接受超声弹性成像检查,以病理诊断结果为金标准,分析联合超声弹性成像后的诊断效能。结果128个结节中,手术病理诊断为恶性结节43个,良性结节85个;在常规超声检查的基础上联合超声弹性成像后的特异度为91.76%,灵敏度为93.02%,诊断准确率为92.19%,与金标准病理诊断的一致性Kappa值为0.829,一致性较高。结论在常规超声检查的基础上,加用超声弹性成像诊断甲状腺结节良恶性的特异度、灵敏度以及诊断准确率均较高。

Objective To discuss the value of ultrasound elastography in the diagnosis of benign and malignant thyroid nodules.Methods Selected 86 patients with thyroid nodules were treated from January 2018 to December 2018 in our hospital with a total of 128 nodules.On the basis of routine ultrasonography,all patients underwent ultrasound elastography and the pathological diagnosis was the gold standard.To analyze the diagnostic efficacy after combined ultrasound elastography.Results Among the 128 nodules,43 were pathologically diagnosed as malignant nodules and 85 benign nodules.The specificity after combined with ultrasound elastography was 91.76%and the sensitivity was 93.02%.The diagnostic accuracy was 92.19%,the Kappa value was 0.829 with the gold standard pathological diagnosis,and the consistency was higher.Conclusion On the basis of conventional ultrasonography,the specificity,sensitivity and diagnostic accuracy of ultrasound elastography in the diagnosis of benign and malignant thyroid nodules are high.
