目的:探讨在甲状腺结节诊断中弹性超声成像的应用价值。方法:对48例甲状腺结节患者(52个甲状腺结节)实施常规超声检查和弹性超声成像检查,以手术组织病理结果为金标准,对常规超声与弹性超声成像的诊断价值进行对比。结果:弹性超声成像结果显示,42个良性结节中,25个为1级,10个为2级,5个为3级,2个为4级。10个恶性结节中,1个为3级,4个为4级,5个为5级。良性与恶性甲状腺结节的硬度分级有显著性差异(P<0.05);常规超声诊断结节良恶性的准确性、敏感性分别为78.8、82.5%,弹性超声成像则为94.2%、94.5%,两种检查方法有显著性差异(P<0.05)。结论:在甲状腺结节疾病的诊断过程中,采用弹性超声成像检查的效果显著。
Objective: To explore the value of elastography in the diagnosis of thyroid nodules. Methods: Forty-eight patients with thyroid nodules (52 thyroid nodules) underwent routine ultrasonography and elastography, and the histopathological results were used as the gold standard to compare the diagnostic value of routine ultrasound and elastography. Results: Elastography showed that of the 42 benign nodules, 25 were grade 1, 10 were grade 2, 5 were grade 3, and 2 were grade 4. Of the 10 malignant nodules, 1 was grade 3, 4 was grade 4, and 5 was grade 5. The grade of benign and malignant thyroid nodules had significant difference (P <0.05). The diagnostic accuracy and sensitivity of conventional ultrasonic diagnosis of nodules were 78.8 and 82.5%, respectively, while those of flexible ultrasound imaging were 94.2% and 94.5% There was a significant difference between the two methods (P <0.05). Conclusion: Echocardiography is effective in the diagnosis of thyroid nodules.
