【摘要】 报告20例自主功能性甲状腺结节显像的诊断意义。9例（99m）^TcO₄^-显像示正常甲状腺组织完全被抑制的病例,8例（99m）^Tc-甲氧基异丁基异腈（MIBI）显像正常甲状腺组织显影清晰;11例正常甲状腺组织不全抑制的病例,（99m）^Tc-MIBI 显像8例显影较（99m）^TcO₄^-显像清晰,3例未见变化。虽然（99m）^Tc-MIBI 显像与 TSH 刺激试验显像的原理不同,但它能使功能受抑制的正常甲状腺组织显影,能够帮助鉴别诊断甲状腺结节的自主功能性,与 TSH 刺激试验比较,具有简便、无过敏反应的优点。更多还原

【Abstract】 PURPOSE The visualization of suppressed thyroid tissue in Plummer’s disease was studied by ^99mTc-MIBI thyroid imaging.METHODS 20 patients of Plummer’s disease with totally or partially suppressed normal thyroid tissue were studied first by ^99mTcO₄^- and then by ^99mTc-MIBI thyroid imaging.RESULTS The suppressed tissue was clearly visualized in 8 out of 9 cases with totally suppressed normal thyroid tissue,while in 11 cases with partially suppressed normal thyroid tissue.The suppressed tissue became clearer in 8 and no change in 3 as compared with their ^99mTcO₄^- imaging.CONCLUSIONS The results suggested that ^99mTc-MIBI thyroid imaging may he used as a substitute for post-TSH stimulation imaging in the diagnosis of Plummer’s dis- ease.This method is relatively simple and has no TSH-related allergic reaction.更多还原
