摘要


Methods: Thyroid imaging was performed on 21 euthyroid females and 16 hyperthyroid females,30 minutes after an intravenous injection of 10mCi (superscript 99m)Tc-tetrofosmin. The ratios of the 30-minute (superscript 99m)Tc-tetrofosmin thyroid uptake were calculated. Results:(A)the ratio of the 30-minute (superscript 99m)Tc-tetrofosmin thyroid uptake has positive relationship with the ratio of the 24-hr 131I 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 (superscript 99m)Tc-tetrofosmin thyroid uptake than those with euthyroidism(4.07±SEM 0.49vs.2.42±SEM 0.10,P<0.005).Conclusion: The 30-minute (superscript 99m)Tc-tetrofosmin thyroid uptake ratio may have potential to diagnose hyperthyroidism.
