【摘要】：目的探讨声触诊组织量化技术(VTQ)在甲状腺实性结节良恶性鉴别诊断中的应用价值。方法采用VTQ技术测量经病理证实的101例患者共129个甲状腺实性结节及周边甲状腺组织剪切波速度(SWV),以病理诊断为金标准,绘制SWV诊断甲状腺实性恶性结节的ROC曲线,获得结节SWV诊断恶性结节的最佳截点。结果甲状腺实性恶性结节的SWV[(3.15±1.91)m/s]大于良性结节[(2.06±0.54)m/s,P0.01]。以SWV=2.43m/s为截点诊断甲状腺实性恶性结节的敏感度、特异度分别为67.80%(40/59)、91.43%(64/70)。甲状腺恶性结节与周边甲状腺组织SWV比值(1.56±0.86)大于良性结节与周边甲状腺组织SWV比值(1.00±0.29,P0.01)。结论 VTQ技术可量化甲状腺结节硬度,对鉴别诊断甲状腺实性结节具有较高的应用价值。
[Abstract]:Objective to evaluate the value of acoustic palpation tissue quantification (VTQ) in differential diagnosis of benign and malignant solid thyroid nodules.Methods VTQ technique was used to measure the shear wave velocities of 129 solid thyroid nodules and surrounding thyroid tissues in 101 patients with pathologically proved solid thyroid nodules. The ROC curve of SWV for diagnosing solid thyroid nodules was drawn according to the gold standard of pathological diagnosis.The optimal point of SWV for diagnosis of malignant nodules was obtained.Results the SWV of thyroid solid malignant nodules [3.15 卤1.91)m/s] was higher than that of benign nodules [2.06 卤0.54 m 路s / s P 0.01].The sensitivity and specificity of SWV=2.43m/s for diagnosis of solid thyroid nodules were 67.80 / 59 / 91.43 / 70 / 70, respectively.The SWV ratio of malignant thyroid nodules to peripheral thyroid tissues was 1.56 卤0.86), which was higher than that of benign nodules to peripheral thyroid tissues (1.00 卤0.29) (P 0.01).Conclusion VTQ technique can quantify the hardness of thyroid nodules and has a high value in differential diagnosis of solid thyroid nodules.
