彩色多普勒超声在健康体检中诊断甲状腺癌的价值

Value of color doppler ultrasound in the diagnosis of thyroid carcinoma in health examination

目的 探讨彩色多普勒超声在健康体检中对甲状腺癌的超声诊断要点及病理符合率.方法选择本院2011～2012年超声怀疑并诊断甲状腺癌患者15例,均有病理结果,回顾分析甲状腺乳头状癌及微小癌声像图表现、超声诊断数与病理符合率及血流信号检测.结果 典型甲状腺癌以低回声结节多见,包膜不明显,边界不规则,无低回声晕,其中11例可见直径〈2mm微小钙化,病灶后方回声衰减4例,颈部淋巴结转移肿大2例,CDFI表现,血流信号2型以上13例,阻力指数〉0.7 12例.本组超声诊断符合率76%.结论彩色多普勒超声在健康体检中对甲状腺癌诊断具有重要的临床价值.

Objective To explore the ultrasonic diagnosis and pathological coincidence rate of thyroid carcinoma by color doppler ultrasound in health examination. Methods The 15 patients with suspected ultrasound diagnosis of thyroid carcinoma from early 2011 to end 2012 in our hospital were selected and all had pathological results, and the sonographic appearance of thyroid papillary carcinoma and minimum cancer, coincidence rate of ultrasound diagnosis and pathological diagnosis and blood flow signal detection were retrospectively analyzed. Results The typical thyroid carcinoma uhrasonography showed mainly hypoechoic nodules, unconspicuous envelope, irregular boundary, no hypoeehoic halo, of which 11 cases with 〈2mm diameter of micro calcification, 4 cases with posterior echo attenuation, 2 cases with cervical lymph nodes metastasis and enlargement, and the CDFI manifestation showed that 13 cases with above 2 type blood flow signals, 12 patients with 〉0.7 resistance index. The ultrasound diagnostic accuracy rate was 76%. Conclusion Color doppler ultrasound has important clinical value in the diagnosis of thyroid carcinoma in health examination.
