^(99m)TC甲状腺显像甲状腺放射性强度的临床意义

The clinical singificance of thyroid radioactive strength with\ 99m Tc Thyroid imaging

目的 观察９９ｍ Ｔｃ 甲状腺显像甲状腺放射性强度在不同甲状 腺疾 病 中的 表 现， 并 分 析其 临 床意 义。 方法 采 用 Ｓ Ｐ Ｅ Ｃ Ｔ 对正常人和不同甲状腺疾病患者８０ 例进行９９ｍ Ｔｃ 甲状腺显像，计算甲状腺的放射性最大计数和平均计数。结果 甲亢组和单纯性甲状腺肿甲状腺放射性最大计数和平均计数均明显高于正常组和甲减组（ Ｐ＜ ０００１） ； 甲亢组和单纯性甲状腺肿组比较，其甲状腺放射性最大计数和平均计数仍高于后者（ Ｐ＜００５） ；正常组与甲减组比，甲状腺放射性最大计数和平均计数无明显差异（ Ｐ ＞ ００５） 。结论 结合患者的临床情况， 对９９ｍ Ｔｃ甲状腺显像的甲状腺放射性强度进行分析，对不同的甲状腺疾病的诊断有一定的帮助。

Objective To Study the thyroid radioactive strength in different thyroid disease with 99m \ Tc Thyroid imaging.Methods SPECT thyroid imaging were studied in four different group,hyperthyroidism(n=37),hypothyroidism(n=9),simple goiter(n=10),normal control(n=24) The thyroid redioactive maximum count (RMC) and average count (RAC) of each group were compared.Results\ The RMC and RAC in hyperthyroidism and simple goiter group were significantly higher than that of control and hypothyroidism group( P <0.001) The RMC and RAC in hyperthyroidism group were also higer than that of simple goite group.But there were nosigniftant difference between hypothyroidism and control group( P >0 05) Conclusion\ The results suggested that with 99m Tc thyroid imaging The thyroid radioactive strength will give some help to differential diagnosis for thyroid diseases.
