核医学检查对早期亚甲炎的诊断价值

The diagnositic value of nuclear medicine for early subacute thyroiditis

目的评价核素显像对于早期亚甲炎的诊断价值。方法对 2 39例早期亚甲炎病人进行甲状腺吸13 1I率、血清甲状腺激素测定及甲状腺显像。结果以吸13 1I率和激素测定结果的“分离现象”为指标 ,诊断符合率为 91 6 % ;甲状腺显像异常影像检出率高达 96 2 %。结论“分离现象”对早期亚甲炎的诊断灵敏度高、特异性强。核素显像在灵敏反映甲状腺功能的基础上 ,能直观显示病变范围及其受损程度 ,从而为早期亚甲炎的诊断及病情评价提供客观依据。

Objective To evaluate the diagnosis value of radionuclide imaging in early subacute thyroiditis.Methods 131 I uptake ratio,thyroid hormone and radionuclide imaging were performed in 239 patients with subacute thyroiditis.Results Using the separate phenomenon as diagnosis standard,the coincidence rates were 91 6%.96 2%patients of radionuclide imaging were abnormal.Conclusion 131 Iuptake ratio and thyroid hormoneare sensitive and specific methods in diagnosis of early subacute thyroiditis.Radionuclide imaging can be used as a sensitive index for judgment of damage intensity of thyroid gland or evaluation of prognosis in patients.
