[摘要] 目的 探讨甲状腺二维和彩色多普勒图像特点，提高早期诊断的准确性。方法 对经手术病理结果证实的70例甲状腺癌患者的术前超声检查结果进行分析，重点分析其内部和边缘的回声特点、血流速度、阻力指数及血流频谱形态。结果 本组病例中单发36例合并结节性甲状腺肿15例，合并腺瘤10例，肿瘤呈不均匀低回声41例，内显示微小钙化点30例，出现液化10例，显示血流丰富19例，难以显示血流信号5例。脉冲多普勒显示平均血流速度25.2cm/s。频谱特点：峰值前移41例，阻力指数平均0.62。结论 超声诊断甲状腺癌主要以下几点：(1)肿块内部呈低回声；(2)肿块边缘无包膜；(3)内部出现钙化灶；(4)后方回声衰减；(5)肿块血流丰富；(6)动脉血流呈高阻力信号；(7)血流频谱峰值前移；(8)颈部转移性淋巴结肿大。如果出现上述中的5点，则可考虑为甲状腺癌。[关键词] 甲状腺肿瘤；超声检查，多普勒，彩色
