动静态显像对亚急性甲状腺炎诊断的应用

Application of dynamic and static imaging in diagnosis of subacute thyroiditis.

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 。

Objective To study the value of dynamic and static imaging in diagnosis of subacute thyroiditis.Methods Dynamic and static imaging of thyroid gland by gamma camera was used in 150 patients with subacute thyroiditis diagnosed in clinic and 50 health volunteers were regarded as the normal control.We also selected 108 patients with hyperthyroidism or other disease of thyroid gland to prepare wityh the experimented and normal groups.Results The blood flow of thyroid gland increased significantly in 43 patients and increased slightly in 50 patients with subacute thyroiditis the phase of imaging became early.These cases were 62 percent of all patients.The blood flow decreased and imaging wasn′t clear in 45 patients which was 30 percent of all cases.The distribution of radioactivity wasn′t regular in thyroid gland in 140 patients which was 93 percent of all patients by static imaging.Conclusions The dynamic and static nuclide imaging presented characteristic changes in subacute thyroidits patients and this may be useful in diagnosis of subacute thyroid.
