亚急性甲状腺炎的彩色多普勒超声诊断价值

目的探讨二维及彩色多普勒超声对亚急性甲状腺炎的诊断价值。方法回顾性分析经细针穿刺活检确诊为亚急性甲状腺炎的65例患者的声像图资料，观察甲状腺病灶的二维图像及彩色多普勒血流分布情况。结果65例患者超声提示为亚急性甲状腺炎57例，诊断符合率87．7％，超声提示为其它甲状腺疾病8倒，误诊率12．3％。超声显示亚急性甲状腺炎病变声像图主要以甲状腺局灶性片状低回声区或结节状低回声为主，病灶周缘血流信号较丰富，内部血流信号稀少。结论彩色多普勒超声对亚急性甲状腺炎的诊断有重要的临床价值。

Clinic vaiue of color doppler ultrasonography in the diagnosis of subacute thyroiditis

Objective To evaluate the value of 2D and color doppler flow imssging（CDFI） in diagnosis of suhacute thyroiditis （SAT） . Methods Retrespetcfive analysis was made on 65 cases with suhacute thyroidifis confirmed by fine needle aspiration biopsy （FNAB） .Results 57 cases out of 65 were diagnosed subacut thyroiditis by ultrasonography. The overall diagnose accordance rate was 87.7%, and the misdiagnosis rate was 12.3%. Suhacute thyroiditis lesions showed heterogeneous hypoecho. More color doppler flow have been found around lesions, no or rare insaid lesions. Conclusion Color dodder Ultrasonography has important clinical value in the diagnosis of subacute thyroiditis.
