前言：本研究的目的在探討是否可利用30分鐘之鎝-99m-tetrofosmin甲狀腺造影來迅速診斷甲狀腺機能亢進症。
方法：包括21個甲狀腺功能正常及16個甲狀腺機能亢進的女性病患於接受10mCi鎝-99m-teirofosmin靜脈注射後，30分鐘進行甲狀腺造影並計算30分鐘甲狀腺攝取鎝-99m-tetrofosmin的比率。
結果：(A)30分鐘鎝-99m-tetrofosmin甲狀腺攝取比率與24小時碘-131甲狀腺攝取比率有正相關，雖然相關性並非十分良好(R=0.589)，(B)甲狀腺機能亢進的病人比甲狀腺功能正常的病人有明顯較高的鎝-99m-tetrofosmin攝取比率(4.07±SEM0.49對2.42±SEM0.10，p<0.005)。
結論：吾人認為30分鐘之鎝-99m-tetrofosmin甲狀腺攝取比率有潛力幫忙診斷甲狀腺機能亢進症。

Methods: Thyroid imaging was performed on 21 euthy- roid females and 16 hyperthyroid females, 30 minutes after an intravenous injection of 10 mci 99mTc-tetrofos- min. The ratios of the 30-minute 99mTc-tetrofosmin thyroid uptake were calculated.
Results: (A) the ratio of the 30-minute 99mTc-tetrofos- min thyroid uptake has positive relationship with the ratio of the 24-hr 'all thyroid uptake, although the correlation was not very good (R = 0.589), and (B) the females with hyperthyroidism had significantly higher ratios of the 30-minute 99mTc-tetrofosmin thyroid uptake than those with euthyroidism (4.07 ±SEM 0.49 vs. 2.42± SEM 0.10, P < 0.005).
Conclusion: The 30-minute 99mTc-tetrofosmin thyroid uptake ratio may have potential to diagnose hyperthyroidism.
