摘　　要：目的探讨超声及超声弹性成像在诊断甲状腺良恶性结节中的价值。方法回顾性分析38例患者(49个甲状腺结节)的超声弹性成像与常规超声特征,以手术组织病理结果为金标准,比较超声弹性成像与常规超声诊断甲状腺良恶性结节的准确性。结果 49个甲状腺结节中良性结节40个,其中弹性成像评级1级24个,2级10个,3级4个,4级2个;恶性结节9个,其中弹性成像评级3级1个,4级3个,5级5个;以弹性成像评级≥4级为界值,超声弹性成像诊断甲状腺恶性肿块的敏感性、特异性、准确性分别为88.9%,95.0%,93.9%。常规超声诊断结节良恶性的敏感性、特异性、准确性分别为75.0%,80.4%,79.6%,二者比较差异有统计学意义(P<0.05)。结论超声弹性成像有助于提高诊断甲状腺结节良恶性的准确性。Objective To explore the value of ultrasonic diagnosis of thyroid benign and malignant thyroid nodules. elasticity imaging and conventional ultrasonography to the Methods The ultrasonic elasticity imaging and conventional ultrasonography characteristics were retrospectively analyzed in 38 patients （49 thyroid nodules）. The diagnostic accuracy was compared between ultrasonic elasticity imaging and conventional ultrasonography on basis of gold standard of operation pathological results. Results In 49 thyroid nodules, 40 were benign nodules including 24 of elastography rating stage 1, 10 of stage 2, 4 of stage 3, and 2 of stage 4; and the other 9 were malignant nodules including 3 of stage 1, 4 of stage 3 and 5 of stage 5. With a cutoff value of elastography rating ≥4, the sensitivity, specificity and accuracy of the ultrasonic elasticity imaging for thyroid malignant tumor were 88. 9%, 95. 0%, and 93. 9%, and of conventional ultrasonography for benign and malignant nodule were 75.0 %, 80.4 %, and 79.6%, which showed significant differences （P〈0. 05）. Conclusion Ultrasonic elasticity imaging is helpful to improving the diagnostic accuracy of malignant and benign thyroid nodules.
