【摘要】 目的　探讨超声对甲状腺癌的诊断价值。方法　对 2 2例甲状腺癌患者进行二维超声及彩色多普勒血流显像 (CDFI)检查 ,全部病例均经手术病理证实。结果　超声图像改变可分为“低回声”型和“混合回声”型。 CDFI显示 :瘤内有较丰富的血供 ,收缩期流速较高 ,频谱增宽 ,阻力指数升高 (RI≥ 0 .70 )。同时可发现颈淋巴结肿大征象。超声诊断符合率为 54.55%。结论　在分析肿块二维声像特征的基础上 ,依据肿块内部血流信号的多少及血流参数测定 ,对甲状腺癌的判断具有重要价值更多还原

【Abstract】 Objective and Methods 22 cases with thyroid carcinomas were diagnosed by 2D and Color Doppler Ultrasonographic examination and confirmed by operation and pathology.Results The sonogram was divided into 2 types, hypoechoic and compound.CDFI showed that there were richer blood supply, higher peak systolic velocity, wide spectrum and higher resistance index(RI≥0.70) in inner artery of tumor.Indirect sign including carotid lymphnode enlargement was found.The coincidence rate of diagnosis with ultrasonography was 54.55%.Conclusion The blood flow message and hemodynamics parameters, which based on the analysing 2D sonogram feature of tumor, had important value to judge the character of thyroid carcinomas.更多还原
