摘要
目的：应用高频超声对甲状腺良恶性结节的声像图特点和彩色多普勒血流信号进行分析和研究，探讨其在良恶性结节的鉴别诊断中的作用。方法：对42例甲状腺结节病人的二维声像图特点进行研究和分析。结果：在彩色多普勒超声探查中恶性结节内部和周边的血流丰富，信号较强，以Ⅱ级或Ⅲ级血流信号为主。而良性结节的血供相对较少，信号较弱，以I级或Ⅱ级血流信号为主。结论：高频超声和彩色多普勒超声对甲状腺良恶性结节的鉴别诊断有重要的作用。
Abstract
Objective: to analyze and study the sonographic features of application of high frequency ultrasound in benign and malignant thyroid nodules and color Doppler flow signal, discusses it in the differential diagnosis of benign and malignant nodules in the role of. Methods: the study and analysis of two-dimensional ultrasonographic features of 42 cases of thyroid nodule patients. Results: the malignant nodules rich, internal and peripheral blood flow in the color Doppler ultrasound signal is strong, with the grade I or II blood flow signals. And benign nodules of the blood supply is relatively less, the signal is weak, with grade I or Ⅱ blood flow signals. Conclusion: high frequency ultrasound and color Doppler ultrasound in the differential diagnosis of benign and malignant thyroid nodules plays an important role in.
