Objective To compare the clinical value of conventional ultrasound imaging and ultrasound elastography in the diagnosis of benign and malignant thyroid nodules. Methods A total of 156 patients (194 nodules) with thyroid nodules were examined by conventional ultrasound imaging and ultrasound elastography. The diagnostic accuracy and the ultrasound elasticity score of benign and malignant patients of the two methods were compared. Results Pathology of nodules showed 44 malignant nodules and 150 benign nodules. The diagnostic accuracy of conventional ultrasound imaging was 85.57％ (166/194) , and the diagnostic accuracy of ultrasound elastography was 93.81％ (182/194). The diagnostic accuracy of ultrasound elastography is higher than that of conventional ultrasound imaging, and the difference is statistically significant (χ2=7.136, P=0.008＜0.05). The difference in ultrasound elastography score between benign and malignant patients was statistically significant (P＜0.05). Conclusion Application of ultrasound elastography shows higher value than conventional ultrasound imaging in diagnosis of benign and malignant thyroid nodules.%目的 比较常规超声成像、超声弹性成像在甲状腺结节良恶性诊断中的临床价值.方法 156例甲状腺结节患者 (194个结节) , 先后进行常规超声成像、超声弹性成像检查, 对比两种方法的诊断准确率及良、恶性患者超声弹性评分情况.结果 结节病理显示恶性44个, 良性150个.常规超声成像的诊断准确率为85.57％ (166/194) , 超声弹性成像的诊断准确率为93.81％ (182/194) , 超声弹性成像诊断准确率高于常规超声成像, 差异具有统计学意义 (χ2=7.136, P=0.008＜0.05) .良、恶性结节超声弹性评分比较差异具有统计学意义 (P＜0.05) .结论 在甲状腺结节良恶性的诊断中采用超声弹性成像比常规超声成像价值更高.
