弹性成像技术结合常规超声在甲状腺结节定性诊断中的价值

Clinical value of combining conve ntional ultrasonic sonography and elastography in diagnosis thyroid nodules

目的：探讨常规超声联合弹性成像在甲状腺结节诊断中的应用价值。方法选择自2010年6月-2013年2月在本院进行甲状腺肿物手术的患者60例,恶性结节共46个,良性结节共37个,行常规超声和超声弹性成像检查,以病理结果为“金标准”,计算常规超声及与弹性超声成像联合诊断甲状腺结节的敏感性、准确性和特异性。结果良性结节的相对硬度低于恶性结节的相对硬度,二者差异有统计学意义[（1.253±0.219）和（2.094±0.754）,χ2=64.816, P=0.0431]；常规超声诊断甲状腺结节的敏感度、特异度、准确性分别为80.4%、78.4%、80.0%；超声弹性成像诊断甲状腺结节的敏感度、特异度、准确性分别为84.7%、86.5%、92.8%；二者联合诊断甲状腺结节的敏感度、特异度、准确性分别为89.1%、91.9%、95.2%。结论常规超声联合弹性成像能提高超声对甲状腺结节良恶性诊断的准确性。

Objective To explore the clinical value of conventional ultrasonic sonography combining elastogrophy in diagnosis of thyroid nodules. Methods Sixty patients with thyroid nodules were selected from June 2010 to February 2013 in our hospital ,which included malignancy 46 cases and benign 37 cases. All the patients were examined with conventional ultrasonic sonography combining elastogrophy, the pathology diagnosis was the regarded as the gold standard, the sensitivity, specificity and accuracy of thyroid carcinoma of conventional ultrasonic sonography or ampho-combination were statistic analyzed. Results The relative hardness of thyroid carcinoma was higher than those of benign thyroid nodules,which was difference significantly[（1.253±0.219）and （2.094±0.754）,χ2=64.816, P=0.0531]. The sensitivity, specificity and accuracy of conventional ultrasonic sonography in diagnosing the thyroid nodules were 80.4%, 78.4%, 80.0%, the elastogrophy were 84.7%, 86.5%, 92.8%,and conventional ultrasonic sonography combining elastogrophy were 89.1%, 91.9%, 95.2%. Conclusion Conventional ultrasonic sonography combining elastogrophy can improve the accuracy of diagnosing the thyroid carcinoma.
