摘　　要：目的探讨超声弹性成像在诊断甲状腺结节中的价值。方法分析2010年2月-2013年2月71例住院患者的119个甲状腺结节超声弹性图,按弹性硬度将其分为5级,0~Ⅱ级判断为甲状腺良性结节,Ⅲ~Ⅳ级判断为甲状腺恶性结节,并与手术后病理检查结果对照。结果依据术后病理检查结果,71例患者119个甲状腺结节中,良性结节102个（85.7%）,恶性结节17个（14.3%）;17个恶性结节超声弹性图均诊断为恶性结节,而102个良性结节仅有75个超声弹性图诊断为良性结节。超声弹性图的诊断灵敏度为100.0%,特异度为73.5%,准确率为77.3%。结论超声弹性成像在甲状腺结节良恶性诊断中有较大的应用价值,结合常规超声检查有助于提高诊断的准确性。Objective To evaluate the clinical value of ultrasonic elastosonography in the diagnosis of thyroid nodules. Methods The elastosonography images of I 19 thyroid nodules in 71 patients treated between February 2010 and February 2013 were analyzed and the hardness of the nodule was classified into five grades according to the results of elastosonography. It was defined that the nodules with grade 0- Ⅱ hardness were benign while those with grade Ⅲ -Ⅳ were malignant. The results of elastosonography were compared with surgery and pathology. Results In these patients, the number of benign and malignant thyroid nodules were 102 and 17, respectively according to pathology. The sensitivity, specificity and accuracy of elastosonography in the diagnosis of thyroid nodules were respectively 100.0%, 73.5% and 77.3%. Conclusion Ultrasonic elastosonography is helpful in the diagnosis between benign and malignant thyroid nodules; the combined elastosonography and conventional ultrasound can improve diagnostic accuracy.
