目的 探讨放射性核素甲状腺动静态显像对亚急性甲状腺炎的诊断价值。方法 对临床确诊的 150例亚急性甲状腺炎患者有γ -照相进行99mTc甲状腺动态和静态显像 ,同时选择 50例健康体查者做正常对照组 ,另选 10 8例甲亢及其它甲状腺疾病一同分析。结果 亚急性甲状腺炎患者中有 4 3例甲状腺血流灌注明显增多 ,50例轻度增多 ,显像时相提前 ,占总数的 62 %。 4 5例甲状腺血流减少 ,显影不清楚 ,占 30 %。静态显像甲状腺腺体内放射性分布呈不均匀者 140例 ,占 93%。结论 亚急性甲状腺炎在核素甲状腺动静态显像中有其特征性改变 ,可做为亚甲炎诊断的常规方法之一
Objective To investigate the diagnostic value of radionuclide thyroid dynamic and static imaging in subacute thyroiditis. Methods A total of 150 cases of subacute thyroiditis were clinically diagnosed by γ - photographic 99mTc thyroid dynamic and static imaging, while 50 cases of healthy people were selected as the normal control group, another 108 cases of hyperthyroidism and other thyroid diseases were analyzed together . Results Thirty-three patients with subacute thyroiditis had a significantly increased blood perfusion of thyroid glands, a slight increase of 50 cases and an early imaging phase, accounting for 62% of the total. Thyroid blood flow reduction in 45 cases, the development is not clear, accounting for 30%. Static imaging of thyroid gland in vivo radioactive distribution was 140 cases, accounting for 93%. Conclusions Subacute thyroiditis has its characteristic changes in nuclide thyroid dynamic and static imaging and can be used as one of the routine methods for the diagnosis of
