超声对甲状腺良恶性结节鉴别诊断的价值

Value of ultrasound in differential diagnosis of benign and malignant thyroid nodules

目的:探讨二维及彩色多普勒超声在甲状腺良恶性结节鉴别诊断中的应用价值。方法:经术后病理证实的80例(105个结节)甲状腺结节性疾病患者术前均经二维声像图、彩色多普勒血流显像方法检查,观察结节的灰阶、彩色多普勒血流显像特征。结果:良性结节70个,恶性结节35个,总的术前诊断准确率为87.62%。结论:应用二维及彩色多普勒超声,可以为甲状腺结节的良恶性进行鉴别诊断,具有较高的临床应用价值。

Objective To estimate the application value of two-dimension and color Doppler flow image（CDFI） in the diagnosis of benign and malignant thyroid nodules.Method Total 80 patients（105 thyroid nodules） proved by pathology,which were examined by preoperative 2D ultrasound and CDFI.Results Of all cases,70 nodules were benign and 35 nodules were malignant.The accuracy rate was 87.62%.Conclusion 2D and color Doppler flow image could be applied to differential diagnosis between benign and malignant thyroid nodules.
