摘　　要：目的探讨亚急性甲状腺炎(SAT)的实时超卢弹性图像特征。方法对26例SAT患者共53个病灶的实时超声弹性图像进行分级,测量并比较弹性图和灰阶超声图显示的病灶面积大小,分析SAT血清T_3、T_4、TSH水平与病灶超声弹性分级的关系。结果 53个SAT病灶的实时超声弹性图像中32个病灶评为Ⅲ级,21个病灶评为Ⅳ级。弹性图显示的病灶面积大于灰阶超声图显示的病灶面积,差异有统计学意义(P<0.05)。SAT血清T_3升高组与正常组、T_4升高组与正常组、TSH减低组与正常组之间病灶的超声弹性分级差异均无统计学意义(P>0.05)。结论 SAT的超声弹性图像具有一定的特征性表现,实时超声弹性成像埘SAT的诊断及鉴别诊断能提供一定信息,但SAT的超声弹性分级不能反映血清T_3、T_4、TSH水平。Objective To evaluate the characteristics of subacute thyroiditis （SAT） on real-time elastosonography. Methods The elastograms of 53 lesions in 26 patients with SAT were analyzed and classified. The areas of lesions on elastograms and on grey-scale ultrasonograms were measured and compared. The relationship between serum T3, T4, TSH levels of SAT and the elastographic grades of lesions were analyzed. Results The elstographic grades of 32 lesions were grade Ⅲ and 21 lesions were grade Ⅳ. The areas on elastograms were statistically larger than those on grey-scale ultrasonograms （P〈0.05） . Statistical results showed there was no significant difference in elstographie grades of lesions between high T3 group and normal T3 group, high T4 group and normal T4 group, low TSH group and normal TSH group （P〉 0.05） . Conclusions Some typical features of SAT on elastosonography are found. Real-time elastosonography can provide some useful information in the diagnosis and differential diagnosis of SAT, but elastographic grades of lesions can not reflect serum T3, T4, TSH levels of SAT.
