目的探讨彩色多普勒超声在诊断亚急性甲状腺炎(SAT)的价值。方法对34例SAT患者共55个病灶的实时超声进行观察,观察肿块的大小、边界、形态及CDFI血流情况。结果根据声像图变化将病程分三期:急性期、中期和恢复期。各期声像图表现在文中进行了描述。34例SAT患者中,双侧叶病灶10例,单侧叶病灶22例,峡部病灶2例;多发病灶19例,单发病例15例。结论彩色多普勒超声检查对提示SAT具有较高诊断价值。
Objective To investigate the value of color Doppler ultrasound in the diagnosis of subacute thyroiditis (SAT). Methods A total of 55 lesions of 34 patients with SAT were observed by real-time ultrasound. The size, boundary, morphology and CDFI blood flow were observed. Results According to the changes of sonography, the course of disease was divided into three phases: acute phase, middle phase and recovery phase. The various stages of sonography are described in the text. Of the 34 patients with SAT, 10 were bilateral leaf lesions, 22 were unilateral leaf lesions and 2 were isthmic lesions; 19 were multiple lesions and 15 were single. Conclusions Color Doppler ultrasound is a valuable diagnostic tool for the diagnosis of SAT.
