摘要目的：探讨声脉冲辐射力成像（ARFI）和超声造影（CEUS）及两者联合应用对实性低回声甲状腺结节的鉴别诊断价值。方法：观察47例甲状腺实性低回声结节患者共62个病灶的术前常规超声、ARFI和CEUS成像特征，以手术后病理结果为标准，评价ARFI、CEUS和两者联合应用对甲状腺实性低回声结节良恶性鉴别诊断的效果。结果：以SWV值≥2.86 m/s作为鉴别甲状腺结节良恶性的诊断界值，诊断的敏感度、特异度、阳性预测值、阴性预测值、准确度分别为82.4％、82.1％、84.8%、79.3%、82.3%。CEUS以弱增强作为诊断甲状腺结节恶性的标准，诊断的敏感度、特异度、阳性预测值、阴性预测值、准确度分别为88.2％、78.6％、83.3%、84.6%、83.9%。ARFI和CEUS联合应用时敏感性94.1%、特异性96.4%、阳性预测值97.0%、阴性预测值93.1%、准确率95.2%，诊断准确率明显高于单独应用（P<0.05）。结论：ARFI和CEUS对甲状腺实性低回声结节具有较高的诊断价值，两种技术的联合应用有助于提高诊断准确性。

Abstract：Objective: To assess the value of acoustic radiation force impulse(ARFI), contrast-enhanced US(CEUS) and their combined application in differential diagnosis of solid hypo-echoic thyroid nodules． Methods: ARFI and CEUS were performed in 47 patients with 62 thyroid nodules. The results of ARFI, CEUS and their combined application, which were classified as benign or malignant ones, were compared with pathological findings. The diagnostic results of ARFI, CEUS and ARFI+CEUS were evaluated and compared． Result: The sensitivity, specificity, PPV, NPV and accuracy of the ARFI for differential diagnosis were 82.4％, 82.1％, 84.8%, 79.3%, and 82.3%, respectively. The sensitivity, specificity, PPV, NPV and accuracy of the CEUS for differential diagnosis were 88.2％, 78.6％, 83.3%, 84.6% and 83.9%, respectively. The sensitivity, specificity, PPV, NPV and accuracy of the ARFI+CEUS for differential diagnosis were 94.1%, 96.4%, 97.0%, 93.1% and 95.2%, respectively. Conclusions: ARFI and CEUS have high value in differential diagnosis of solid hypo-echoic thyroid nodules, the combined application of two methods can be helpful to improve the diagnostic accuracy．
