目的：：探讨超声弹性成像( UE)在甲状腺良恶性小结节诊断中的价值。方法：收集甲状腺小结节138个，以病理检查结果为标准，对比UE及常规超声检查对甲状腺小结节良恶性鉴别诊断效能。结果：经病理证实的138个甲状腺小结节(直径≤1 cm的)良性结节96个，恶性结节42个。 UE、常规超声对甲状腺实性小结节良恶性诊断的敏感度、特异度、准确性分别为95.2%、86.5%、89.1%和78.6%、83.9%、79.0%。结论：UE主要通过检测甲状腺小结节的硬度来鉴别诊断良恶性，其敏感性、准确性明显高于常规的超声检查，但部分甲状腺良恶性结节硬度间仍存在一定的重叠现象，故还须结合常规超声检查进行综合性诊断，以增加诊断的准确性。

Objective: To investigate the diagnosis value in benign and malignant thyroid nodules by ultrasound elastography. Methods:138 thyroid nodules were collected. The pathological examination results as a standard, the efficacy in differential diagnosising benign and malignant thyroid nodules by UE or conventional ultrasound were compared. Results:Among 138 thyroid nodules(diameter≤1 cm)which were confirmed by pathology, there were 96 benign nodules and 42 malignant nodules. The diagnosis sensitivity, specificity, accuracy of benign or malignant thyroid solid nodule by UE, conventional ultrasonography were 95. 2%, 86. 5%, 89. 1% and 78. 6%, 83. 9%, 79%, respectively. Conclusion:UE is mainly through detecting thyroid nodules’ hardness for differential diagnosising benign or malignant. Its sensitivity, accuracy are significantly higher than those of conventional ultrasonography, but there are some benign and malignant thyroid nodules hardness which is still overlaped, so it needs to combine with conventional ultrasonography for incomprehensive diagnosis, in order to increase diagnosis accuracy.
