摘　　要：目的:探讨二维及高频彩色超声在甲状腺癌诊断中的应用价值。方法:搜集经手术病理证实的57例甲状腺癌,回顾分析二维及彩色多普勒检查结果,着重分析甲状腺肿块内部回声的特点、肿块的大小、形态、边缘、钙化、有无包膜和肿块彩色血流丰富程度、频谱多普勒中的多项测量指标的变化以及颈部淋巴结转移情况。结果:57例甲状腺癌患者中,实性低回声结节42例,囊实性混合结节15例,结节边界不清晰33例,结节中有砂砾样钙化灶31例,颈部淋巴结转移24例,51例彩色多普勒血流显像(CDFI)检出结节内及周边探及血流信号。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。Aim： To appreciate the value of ultrasonography in the Methods： Fifty-seven cases of thyroid carcinoma, proven by pathology and peration, were analyzed the two-dimensiona and high-frequency sonography. Emphasis was put on the feature of internal echo, the size, the shape, the borderline, the calcification of tumor, and the plentiful degree of color flow, the measuring indexs＇ change in frequency spectrum Doppler and the cervical lymph nodes. Results： In 57 thyroid carcinoma cases, 42 showed hypoechoic solid nodules, 15 showed cysticsolid complex nodules, 33 showed indistinctly defined borders, 31 had sandy calcification loci, 24 cases had metastatic lymphnodes of neck, solid nodules, and color doppler blood flow signals were seen both in the loci and on borders in 51 cases. Conclusion： Ultrasonic characteristics of thyroid carcinoma are specific, the correct diagnosis rate of thy- roid carcinoma can be raised by use of combination of two-dimensional ultrasound and color doppler flow imaging.
