超声弹性成像应变率比值法与弹性成像分级法在甲状腺良恶性结节鉴别诊断中的价值比较

Comparison on the elastography strain rate ratio and elastic imaging classification in differential diagnosis of benign and malignant thyroid nodules

目的:探讨超声弹性成像应变率比值法与弹性成像分级法在甲状腺良恶性结节鉴别诊断中的临床价值。方法:收治甲状腺结节疾病患者200例,均采用弹性应变率比值法和弹性分级法检查甲状腺结节。结果:两种方法检查甲状腺良、恶性结节差异有统计学意义(P<0.05);超声弹性成像应变率比值法诊断符合率明显高于超声弹性成像分级法(P<0.05)。结论:超声弹性成像应变率比值法对甲状腺良恶性结节的鉴别诊断价值明显优于弹性分级法。

Objective：To investigate the clinical value of ultrasonic elastography strain rate ratio and elastic imaging classification in the differential diagnosis of benign and malignant thyroid nodules.Methods：200 patients with thyroid nodule disease were treated with elastic strain rate ratio method and elastic classification method.Results：The difference between the two methods in detecting benign and malignant thyroid nodules was statistically significant（P〈0.05）;the diagnostic coincidence rate of ultrasonic elastography strain rate ratio was significantly higher than that of ultrasonic elastography classification（P〈0.05）.Conclusion：The elastography strain rate ratio method is superior to the elastic classification in the differential diagnosis of benign and malignant thyroid nodules.
