摘　　要：目的研究超声弹性成像(ultrasound elasticity imaging,UE)七分法及声脉冲辐射力(acoustic radiationforce impulse,ARFI)成像技术对甲状腺良恶性结节鉴别诊断的价值。方法对76例患者100个甲状腺结节采用UE七分法进行评价,用ARFI定量测定结节内剪切波速度(shear wave elocity,SWV),以病理诊断作为金标准,评价两种方法的诊断价值。结果诊断甲状腺良恶性结节,UE七分法的最佳分界点为评分≥5,灵敏度为55.0%,特异度为92.5%,准确率为85%;ARFI最大SWV值的最佳诊断分界点为4.25,灵敏度为55%,特异度为95%,准确率为87%;中位数SWV值的最佳诊断分界点为2.57,灵敏度为70.0%、特异度为82.5%,准确率为80.0%。结论 UE七分法及ARFI均对甲状腺良恶性结节的鉴别诊断具有一定价值,方法间无明显差异。Objective To study the differential diagnosis value on thyroid nodules of ultrasonic elasticity imaging （UE） seven points method and acoustic radiation force impulse （ARFI） imaging technique. Methods A total of 100 thy- roid nodules in 76 patients were evaluated by using UE seven points method. ARFI quantitative method was utilized to de- termine the shear wave velocity （SWV） of the nodule. Pathological diagnosis was as the gold standard to evaluate the di- agnosis value of the two methods. Results For the diagnosis of benign and malignant thyroid nodules, the optimal cut-off score of UE seven points method was ≥5, the sensitivity was 55.0%, the specificity was 92. 5% and the accurate rate was 85.0% ; the optimal cut-off point for the maximum SWV of ARFI was 4. 25, the sensitivity was 55.0%, the specific- ity was 95.0~ and the accurate rate was 87. 0% ; the optimal cut-off point for the medium SWV of ARFI was 2. 57, the sensitivity was 70. 0%, the specificity was 82. 5% and the accurate rate was 80. 0%. Conclusion UE seven points method and ARFI have certain differential diagnosis value on benign and malignant thyroid nodules and they have no obvious difference.
