目的 评价超声、核素影像学在亚急性甲状腺炎诊断中的作用。方法 回顾性分析了经病理或临床明确诊断为亚甲炎 47例患者的超声、核素影像表现及特点。结果 47例中 ,Ⅰ、Ⅱ型 37例 ,超声特征 33例为片状低回声 ,5例为回声不均质性增强 ,并点片状低回声灶 ,正确诊断率为 91.9% (34 / 37)。核素扫描为甲状腺不显影或显影不清 ,正确诊断率为 81.1% (30 / 37)。两种结果有较好一致性 (χ2 =2 2 .97,P <0 .0 0 1)。Ⅲ型 7例 ,超声甲状腺呈结节样不规则增大 ,正确诊断率为 71% (5 / 7)。核素显影甲状腺本底高伴凉结节或显影分布不均。结论 超声显像及核素扫描各有其特异性 ,在Ⅰ、Ⅱ型中 ,两种检查结果有较好的一致性。在Ⅲ型中 ,超声需与肿瘤鉴别 ,核素无特异性
Objective To evaluate the role of ultrasound and radionuclide imaging in the diagnosis of subacute thyroiditis. Methods Retrospective analysis of 47 cases of methylene blue inflammation or pathologically confirmed by clinical manifestations and features of ultrasound images. Results Among the 47 cases, 37 cases were type Ⅰ and Ⅱ, and 33 cases were echographic hypoechoic. Among them, 5 cases had hypoechoic echogenicity and some pelvic hypoechoic lesions. The correct diagnosis rate was 91.9% (34/37 ). Radionuclide scan was not developed or undeveloped thyroid, the correct diagnosis rate was 81.1% (30/37). There was a good agreement between the two results (χ2 = 2 2 .97, P <0 0 01). Ⅲ type in 7 cases, sonography showed nodular irregular increase, the correct diagnosis rate was 71% (5/7). Radionuclide development with high thyroid gland or nodular uneven distribution of development. Conclusion Ultrasound imaging and radionuclide scanning each have their own specificity. In type Ⅰ and type Ⅱ, the results of the two tests are in good agreement. In the type Ⅲ, ultrasound and tumor identification, non-specific nuclide
