目的 :评价彩色多普勒超声在甲状腺癌诊断中的作用。方法 :选取2013年1月~2014年1月我院收治甲状腺癌患者42例作为研究组,对手术前患者CDFI超声图像进行研究,对病灶内部回声、形态、钙化情况及周边血流分布情况进行观察,同时选取42例甲状腺良性疾病患者作为对照组,比较两组血流动力学参数。结果 :甲状腺癌病灶66.7%呈低回声;73.8%患者病灶内呈微钙化现象,边界不规则,多呈蟹足样或有明显毛刺状,88.1%血流束粗细不等、走形僵硬;研究组血流速度及阻力指数较对照组显著提高,组间差异均具有显著统计学意义。结论 :甲状腺癌具有明显的超声图像特征,采用彩色多普勒超声对甲状腺癌诊断具有重要的诊断价值。
Objective: To evaluate the role of color Doppler ultrasound in the diagnosis of thyroid cancer. Methods: From January 2013 to January 2014, 42 patients with thyroid cancer in our hospital were selected as study group. The CDFI ultrasound images of the patients before operation were studied. The echogenicity, morphology, calcification and distribution of peripheral blood flow were studied 42 cases of thyroid benign disease were selected as the control group, and the hemodynamic parameters were compared between the two groups. Results: 66.7% of thyroid cancer lesions showed hypoechoicity; 73.8% of patients showed microcalcifications in lesion with irregular border, mostly crab-like or obvious burr, 88.1% Group blood flow velocity and resistance index increased significantly compared with the control group, the differences between groups were statistically significant. Conclusion: Thyroid cancer has obvious features of ultrasound images. Color Doppler ultrasound has important diagnostic value in the diagnosis of thyroid cancer.
