目的 :评估核医学在亚急性甲状腺炎诊断中的价值。方法 :对 113例亚急性甲状腺炎患者的有关检查结果进行了分析 ,所有患者均进行TT3、TT4 、TSH及TGA、TMA的血清学检测 ,同时进行甲状腺吸131Ⅰ功能测定和甲状腺显像检查。结果 :亚甲炎患者都有不同程度的血清激素水平的改变 ,6 0 %以上患者发病之初TT3、TT4升高 ,95 .5 %的甲状腺吸131Ⅰ率降低 ,典型特征的分离现象为 6 5 % ,甲状腺显像异常的达 96 .5 %。结论 :在亚甲炎的诊断中以核医学检查甲状腺显像和甲状腺吸131Ⅰ率的灵敏度最高 ,优于血清激素浓度的测定 ,而两者结合 ,诊断亚甲炎更为准确可靠。
Objective: To evaluate the value of nuclear medicine in the diagnosis of subacute thyroiditis. Methods: The results of 113 cases of subacute thyroiditis were analyzed. All patients were serologically tested for TT3, TT4, TSH, TGA and TMA. Thyroid 131I function and thyroid imaging were also performed. Results: The levels of serum hormones in patients with different doses of methylene blue were significantly different from those in patients with mild hypothyroidism. The levels of TT3 and TT4 in the over 60% patients were elevated at 95% %, Abnormal thyroid imaging up to 96.5%. Conclusion: The sensitivity of nuclear medicine to thyroid imaging and thyroid uptake 131 Ⅰ in the diagnosis of methylene blue inflammation is the highest, which is superior to the determination of serum hormone concentration. The combination of the two can be more accurate and reliable for the diagnosis of methylene.
