摘　　要：目的对比分析超声造影与弹性成像诊断良恶性甲状腺结节的应用价值。方法选择2010年7月至2014年1月收治的164例患者,采用常规超声检查、超声造影以及彩色多普勒血流成像检查,观察并详细记录所发现的甲状腺病灶的内部与周边血流、内部回声特征、直径、钙化程度及位置等信息。以手术病理结果为金标准,比较常规超声、超声造影、弹性成像对良、恶性甲状腺结节诊断的准确性。结果 164例患者共328个病灶结节,其中良性结节192个,恶性结节136个。超声造影、弹性成像及二者联用对良、恶性甲状腺结节的阳性预测值、阴性预测值、敏感度及特异度均明显优于常规超声诊断结果(P<0.05);而超声造影、弹性成像比较,差异无统计学意义(P>0.05)。超声造影联合弹性成像的诊断灵敏度明显高于超声造影、超声弹性成像(P<0.05)。结论超声造影、弹性成像对良恶性甲状腺结节诊断价值高,二者联合可进一步提高诊断灵敏度。Objective To compare the diagnostic value of ultrasound imaging and elasticity ima- ging for benign and malignant thyroid nodules. Methods Conventional ultrasound,ultrasound imaging and color Doppler flow imaging were used on 164 patients to observe and record the inside and peripheral blood flow,internal echo characteristic, diameter,calcification,location and so on. Surgical pathology results were taken as the gold standard for benign and malignant thyroid nodules and compared the diagnostic accuracy of conventional ultrasound,ultrasound imaging and elastography. Results 168 patients had 328 thyroid nod- ules,and there were 192 benign nodules and 136 malignant nodules. Ultrasound imaging, elastography and combined the two methods together were significantly better than conventional ultrasound in positive predic- tive value,negative predictive value,sensitivity and specificity（P 〈 0. 05）. As for ultrasound imaging and elastography, there was no statistical differences （ P 〉 0. 05 ）. Diagnostic sensitivity of ultrasound imaging combined elastography was significantly higher than conventional ultrasound and ultrasound elastography （ P 〈 0. 05 ）. Conclusion There is high value of using ultrasound imaging, elastography for the diagnosis of benign and malignant thyroid nodules. Combined the two methods together can further improve the diagnos- tic sensitivity.
