摄碘率与甲状腺显像在无痛性甲状腺炎诊断中的应用

目的 探讨摄碘率与甲状腺显像在无痛性甲状腺炎(PT)诊断中的应用价值.方法 对2008年1月至2010年6月在我院就诊的70例PT、50例Graves病(GD)患者和50例健康体检者的摄碘率、甲状腺显像和血清学检查进行回顾性对比分析.结果 PT组3 h摄碘率、24 h摄碘率明显低于健康对照组,GD组3 h摄碘率、24 h摄碘率明显高于健康对照组,PT组和GD组比较差异有极显著性意义(F=64.88,P＜0.01);70例PT患者甲状腺轮廓显示不清晰,部分患者未见甲状腺显影,而50例GD患者甲状腺全部显像,甲状腺轮廓清晰可见.结论 摄碘率与甲状腺显像可以准确反映甲状腺病变的受累及范围、程度和功能状态,在PT诊断中起决定性作用,是目前鉴别PT与GD不可替代的简便而又有效的方法.

Value of radioactive iodine uptake and thyroid imaging in diagnosis of painless thyroiditis

Objective To evaluate clinical value of radioactive iodine uptake and thyroid imaging in diagnosis of painless thyroiditis(PT). Methods Seventy cases of PT patients, 50 cases of GD patients and 50 cases of healthy persons were retrospectively analyzed by using radioactive iodine uptake, thyroid imaging and serological examination. Results PT group radioactive iodine uptake rate was significantly lower than the control group, GD group was significantly higher than the control group, PT group and the GD group difference was significant (F=64.88, P＜0.01). Thyroid image of PT group is not clear, or no to be seen, thyroid image of GD group can be clearly visible. Conclusion Radioactive iodine uptake and thyroid imaging play an irreplaceable role in the identification of PT and GD, and the method is simple and effective too.
