摘　　要：目的:探讨二维声像图(二维)及彩色多普勒(CDFI)超声诊断甲状腺癌的应用价值。方法:对经手术及病理证实的49例甲状腺癌的二维及彩色多普勒超声表现进行分析。结果:本组49例一共53个病灶超声检出率为94.3%(50/53),诊断符合率77.4%(41/53),误诊、漏诊率22.6%(12/53)。甲状腺癌声像图表现为:形态不规则、边界不清晰、周边无声晕,内部不均匀低回声、伴微钙化、后方回声衰减、颈部淋巴结肿大、肿物内血流丰富、以高阻力为特征。结论:结合二维及彩色多普勒超声检查有助于提高甲状腺癌的诊断,为手术治疗提供有价值的依据。Objective：To probe into the application value of 2-dimensional ultrasonic gram （2 DUS） and color doppler flow imaging （CDFI） in the diagnosis of thyroid cancer.Methods：The features of 2 DUS and CDFI of 49 cases patients with thyroid cancer, who had been confirmed operationally and pathologically, had been analyzed.Results：Of the 53 focuses in 49 cases of patients, 94.3% （50/53） was checked out by ultrasound with rate of conformity of 77.4% （41/53） and misdiagnosis or missing diagnosis rate of 22.6%（12/53）.The uhrasonographical features of thyroid cancer were as below：irregular shape,unsharp edge,no peripheral sonic halo,internal unevenness,low echo,slight calcifying,weakening of echo in rear and swelling of lymph node in neck with sufficient blood flow within the swelling and characterized with high resistance. Conclusion：With the 2 DUS and CDFI added,the diagnosis rate of thyroid cancer would be promoted, so as to provide the valuable basis for the operation.
