目的探讨彩色多普勒超声在甲状腺癌诊断中的应用价值。方法回顾性分析2012年1月至2013年12月间收治的65例经病理确诊的甲状腺癌患者的二维与彩色血流图像。结果共发现80枚肿块,肿块大小为5.1mm×6.2mm至66.5mm×48.0mm,平均大小为25.0mm×23.0mm。超声图像显示,肿块边界不规则,且无包膜,周边无任何声晕;部分出现不均匀回声,或者稍低回声,混合性回声。彩色多普勒超声结节显示有血流信号,且表现中心性和穿入性血流,血流信号的多少与患者病灶大小相关,结节越大其血流信号越丰富,且比较复杂。结节血流分级显示,Ⅰ级10例(15.4%),Ⅱ级28例(43.1%),Ⅲ级27例(41.5%)。PSV为10.5cm/s至50.0cm/s,流速为(30.4±3.5)cm/s;RI为0.42~0.99,平均RI为0.71。结论彩色多普勒超声在甲状腺癌诊断中具有重要价值,二维和彩色多普勒超声能够有效提高诊断符合率。
Objective To explore the value of color Doppler ultrasound in the diagnosis of thyroid cancer. Methods A retrospective analysis of two-dimensional and color flow images of 65 patients with pathologically confirmed thyroid cancer admitted between January 2012 and December 2013 was performed. Results A total of 80 tumors were found. The tumor size ranged from 5.1 mm × 6.2 mm to 66.5 mm × 48.0 mm with an average size of 25.0 mm × 23.0 mm. Ultrasound images showed irregular masses with no capsule and no peripheral halo; some with non-uniform echoes, or slightly hypoechoic, mixed echoes. Color Doppler ultrasound nodules showed a blood flow signal, and the performance of central and penetrating blood flow, the number of blood flow related to the size of the lesion patients, the greater the nodules its blood flow signal richer, and more complicated. The nodular blood flow classification showed that grade Ⅰ was 10 (15.4%), grade Ⅱ 28 (43.1%), and grade Ⅲ 27 (41.5%). The PSV ranged from 10.5 cm / s to 50.0 cm / s with a flow rate of (30.4 ± 3.5) cm / s; RI ranged from 0.42 to 0.99 with an average RI of 0.71. Conclusion Color Doppler ultrasound is of great value in the diagnosis of thyroid cancer. Two-dimensional and color Doppler ultrasound can effectively improve the diagnostic coincidence rate.
