目的探讨彩色多普勒超声诊断甲状腺微小癌(TMC)的临床价值。方法总结分析2000年1月～2010年1月间在我院接受手术切除的TMC患者60例的临床超声声像资料。结果本组检出的甲状腺微小癌大小为3mm～11mm,为圆形或椭圆形,多无包膜;结节内可见细小钙化;肿块周边或内部可见动脉血流信号。收缩期峰值流速8.8cm/s～35cm/s,阻力指数0.6～0.8。乳头状癌50例,滤泡状癌6例,髓样癌4例,诊断符合率91.67%。结论彩色多普勒超声诊断甲状腺微小癌的临床价值较大,值得首先选用。
Objective To investigate the clinical value of color Doppler ultrasonography in the diagnosis of thyroid microcarcinoma (TMC). Methods The clinical data of 60 patients with TMC undergoing surgical resection in our hospital from January 2000 to January 2010 were analyzed. Results The group of thyroid cancer detected in the size of 3mm ~ 11mm, round or oval, and more non-enveloped; visible nodules within the calcification; visible mass within or around the artery flow signal. Systolic peak flow rate 8.8cm / s ~ 35cm / s, resistance index 0.6 ~ 0.8. Papillary carcinoma in 50 cases, follicular carcinoma in 6 cases, medullary carcinoma in 4 cases, the diagnostic coincidence rate was 91.67%. Conclusion The clinical value of color Doppler ultrasonography in the diagnosis of thyroid microcarcinoma is larger and it is worth choosing first.
