甲状腺本身病变所致甲亢的核素显像特征

目的甲状腺功能亢进症具有多种病因、临床表现和治疗方法。应用核素显像对甲状腺自身病变所致甲状腺功能亢进症病因进行正确的诊断，指导选择相对应合适的治疗方法。方法319例临床拟诊甲亢患者，治疗前进行甲状腺显像（thyroid radionuclide imaging），对甲亢病因做分型。结果甲状腺显像特征分类Grave’s病（GD）259例（合并结节66例），81．2％；毒性腺瘤（TA）36例，11．3％；毒性多结节性甲状腺肿（TMNG）9例，2．8％；亚急性甲状腺炎15例，4．7％。结论甲状腺核素显像在甲状腺功能亢进症的分类和指导治疗中起重要的基础作用，可为临床提供合理及最佳的临床实践。

The character of nuclide imaging of the hyperthyroidism due to disorders with thyroid gland

Objective The objectives were to observe character and practice of thyroid radionuclide imaging in the diag nosis of hyperthyroidism cause of thyrotoxicosis thyroid disorders with thyroid gland and to guide the selection of corre sponding treatment. Methods Thyroid radionuclide imagings were carried out on 319 patients suspiciouly diagnosed as hy perthyroidism before therapy, then classified as 4 types of Graves＇ disease （GD）, toxic multinodular goiter （TMNG）, toxic adenoma （TA）, and suhacute thyroiditis. Results The diagnostic categories were Graves＂ disease （GD, n=259, co existing with nodules n=66, 81.2%） ; solitary toxic adenoma （TAn=36, 11.3%） ; toxic multinodular goitre （TMNG, n = 9, 2.8%）; subacute thyroiditis （n= 15, 4.7 0%）. Conclusion Thyroid nuclide imaging plays an essential role in the di agnosis of hyperthyroidism and management of patients with hyperthyroidism.
