摘　　要：[目的]探讨运用二维超声(2D)、彩色多普勒血流显像(CDFI)、频谱多普勒(PW)、三维彩色血流能量图(3D-CPA)诊断甲状腺结节良恶性的价值。[方法]分析89例甲状腺结节患者的2D、CDFI、PW、3D-CPA,并与手术病理结果对照。[结果]甲状腺良恶性结节在边界、形态、钙化、声晕、血流分级、最大峰值流速PSV、阻力指数RI方面均有显著性差异。3D-CPA结合CDFI能更清晰地显示甲状腺结节空间及内部的血流特征。[结论]综合运用2D、CDFI、PW、3D-CPA能明显提高甲状腺结节诊断的准确率。[Purpose] To explore the value of two-dimension uhrasound（2D）, color doppler flow imaging （CDFI）, pulse wave doppler （PW） and three-dimension color power angiography （3D-CPA） in differentiating malignant from benign thyroid nodules. [Methods ] The uhrasonography features including 2D, CDFI, PW and 3D-CPA finding in 89 cases with thyroid nodules were analyzed and compared with pathological results. [Results] There were significant difference between malignant and benign thyroid nodules in boundary, appearance, calcification, acoustic halo, blood grading, PSV and RI. 3D-CPA combined with CDFI could clearly show the blood feature of thyroid nodules. [Conclusion ] Combination of 2D, CDFI, PW and 3D-CPA images can improve the diagnostic accuracy for thyroid nodules.
