摘　　要：目的探讨高频彩超在甲状腺癌诊断中的应用价值。方法对经手术及病理证实的30例甲状腺癌和20例甲状腺瘤二维及彩色多普勒(CDFI)超声表现进行分析比较。结果甲状腺癌表现的周边无声晕、低回声及微钙化检出率分别为80%、76.7%、63.3%,甲状腺癌的血供以高阻力为特征,与甲状腺瘤差异有统计学意义(P<0.01)。结论甲状腺癌的超声表现具有一定的特征性,综合分析二维声像图及CDFI表现,有利于提高甲状腺癌超声诊断的正确率。Objective To evaluate the diagnostic value of thyroid carcinoma by high frequency color Doppler uhrasonography. Methods Thirty cases with thyroid carcinoma and 20 cases with thyroid adenoma, confirmed by pathology were analyzed comparatively with two-dimensional and color Doppler flow imaging （CDFI）. Results The characteristics of thyroid carcinoma showed no halo sign in 80%, hypoerchoic in 76.7%, and mierocalcifieation in 63.3%. CDFI showed rich blood signals with high resistance index in thyroid carcinoma. There were significant differences in two-dimensional image and CDFI between two-dimensional and thyroid adenoma. Conclusion Ultrasonic characteristics of thyroid carcinoma are specific; the correct diagnosis rate of thyroid carcinoma can be raised by the combing of two-dimensional ultrasound and color Doppler flow imaging.
