摘　　要：目的探讨彩色多普勒超声在甲状腺结节性病变诊断中的意义。方法采用LOGIQ7超宽频全数字彩色声像仪检查甲状腺结节的彩色多普勒血流图及多普勒频谱,同时与病变的核素及病理结果对比分析。结果结节内RI>0.7有助于良恶性的鉴别,其敏感性为73.7%,特异性为92.8%,准确性为89%;峰值流速及血流信号的丰富与否对良恶性鉴别无统计学意义;血流丰富的凉结节或冷结节多提示腺瘤或癌;初步发现恶性肿瘤血流信号的多少似乎与肿瘤的组织类型有关。结论彩色多普勒超声在甲状腺结节性病变的诊断中有非常重要的价值。Objective To evaluate the significance of color Doppler flow imaging（CDFI）in the diagnosis of thyroid nodules.Methods The comparisons were performed with the results of CDFI by LOGIQ 7,radionuclide imaging results and the pathological results in thyroid nodule patients.Results The result was that RI〉0.7 was a useful aid in the diagnosis of benign and malignant thyroid nodules.The sensitivity was 73.7%,with a specificity of 92.8%and an overall accuracy of 89%.There was no significant difference between benign and malignant nodules by peak velocity and the degree of the blood flow.Cold nodules with rich blood were always suggestive of adenoma or carcinoma.The preliminary found was that the number of blood flow signals in malignant nodules seemed to have a relationship with the organization type of the tumors. Conclusion CDFI is significant in the diagnosis of thyroid nodules.
