Objective To investigate the clinical applications value of ultrasound diagnosis for thyroid follicular carcinoma and medullary carcinoma. Methods From January 2006 to December 2012 in our hospital, selected 66 patients with thyroid follicular carcinoma and medullary carcinoma, included 38 cases of thyroid follicular carcinoma and 28 cases, medullary carcinoma and above-mentioned cases were accepted ultrasound examination. Results 38 cases of follicular thyroid cancer were mainly in real mass (35/38, 92.1%), the real performance was mass echogenic (19/35, 54.3%) and hypoechoic echogenic (16/35, 45.7%), the border was clear (28 cases). 10 cases had enveloped, incomplete hypoechoic halo, no calcification. The blood flow distribution of follicular thyroid cancer: 0 grade had 1 case, I grade had 16 cases, Ⅱ grade had 8 cases, Ⅲ grade had 13 cases. Flow spectrum was low resistance, RI=0.53-0.58.The dimensional sonographic features of medullary thyroid carcinoma mostly were solid hypoechoic and internal uneven distribution and posterior echo attenuation,no calcification (14 cases), had no or no full sound dizzy, and nodule had calcification, especially was sand like calcification.Cervical lymph node metastasis was more common(71.4%, 20/28),and mostly were bilateral.28 cases of patients with nodular peripheral and internal flow signals were seen more abundant, were mainly peripheral distribution, mostly intermittent annular flow to venous flow-based, where 0 grade had 1 case, Ⅰgrade had 4 cases, Ⅱgrade had 6 cases, Ⅲgrade had 17 cases.Resistance index(RI) was 0.55-0.82. Conclusion Ultrasound diagnosis of thyroid follicular carcinoma and medullary carcinoma has a convenient, efficient, painless, non-invasive characteristics advantages, sonographic features by ultrasound can accurately assess lesion characteristics, and combined with the pathological findings to provide guidance for the diagnosis for thyroid cancer basis.%目的：探讨超声诊断甲状腺滤泡状腺癌和髓样癌的临床应用价值。方法2006年1月~2012年12月我院共收治甲状腺滤泡状腺癌和髓样癌患者66例，其中甲状腺滤泡状腺癌38例，髓样癌28例，对上述病例分别进行超声检查。结果38例滤泡状甲状腺癌以实质肿块为主（35/38，92.1％），实质肿块表现为等回声（19/35，54.3％）及低回声（16/35，45.7％），边界尚清晰（28例），10例有包膜，不完整低回声晕，未见钙化。甲状腺滤泡状癌的血流分布：0级1例，I级16例，Ⅱ级8例，Ⅲ级13例。血流频谱呈低阻，阻力指数（RI）为0.53~0.58。甲状腺髓样癌二维声像特征多呈实性低回声，内部分布不均，后方回声衰减，边界不清（14例），无或无完整声晕，结节内可见钙化，特别是沙粒样钙化灶。颈部淋巴结转移多见（71.4%，20/28），且多为双侧。28例患者结节周边及内部均可见较丰富血流信号，周边分布为主，多为断续环状血流，以静脉血流为主，其中0级1例，Ⅰ级4例，Ⅱ级6例，Ⅲ级17例。阻力指数（RI）为0.55~0.82。结论超声诊断甲状腺滤泡状腺癌和髓样癌具有便捷、高效、无痛、无创的特点，优势明显，通过超声的声像图特征可以较准确评估病变的特征，并结合病理检查结果为甲状腺癌的诊断提供指导依据。
