桥本氏甲状腺炎的彩色超声声像图分析

Diagnosis of Hashimoto's thyroiditis with color Doppler flow imaging

目的探讨桥本甲状腺炎(HT)的声像图特征。方法回顾性分析经病理、针吸细胞学及实验室检查确诊的60例HT患者的声像图特征。结果①HT的声像图特征可分为4种类型,即局限型(9例)、结节型(6例)、弥漫型(21例)和弥漫型并结节(24例);②不同声像类型甲功减低的发生率不同;③弥漫型并结节中的HT结节可由弥漫型发展而来,药物干预后结节可逐渐消失而再次转回为弥漫型HT;④弥漫型及弥漫型并结节的HT共45例,其腺体血供均出现不同程度增多,但仅14例呈"火海征"。结论彩色多普勒超声可以对声像图复杂的HT做出比较准确的诊断。

Objective To investigate the color Doppler flow imaging（CDFI）characteristics of Hashimoto＇s thyroiditis（HT）,so as to elevate diagnostic accordance rate.Methods The sonographic characteristics of HT and complications confirmed by histology,cytology and laboratory were retrospectively analyzed in 60 patients.Results Echographic patterns of HT were generalized as four types：topical type（9 cases）,nodular type（6 cases）,defuse type（21 cases）and diffuse ＆ nodular type（24 cases）.Each type had different incidence rate of hypothyroidism.HT-nodulars in diffuse ＆ nodular type could develop from diffuse type,but after medication some of them disappeared and transformed again to diffuse type.The blood flow of 45 cases increased in different level,while ＂flames sea sign＂ was observed only in 14 cases.Conclusion CDFI can provide comparatively accurate diagnosis for HT.
