Thyroidal 99mTcO4- (pertechnetate) uptake percentages were determined in unanesthetized euthyroid (n = 13) and hyperthyroid (n = 18) cats. Maximal uptakes were observed 60 minutes after IV injection of the radionuclide and ranged from 0.3 to 3.9% of the dose in euthyroid cats (median 2.23%) and from 5.2% to 23.9% of the dose in hyperthyroid cats (median 14.8%) (P < .05). There were no overlaps in pertechnetate uptake percentages during any of the intervals evaluated. It is concluded that the optimal time for visualization of the thyroid by 99mTcO4(-)-scanning is 60 minutes after IV injection of the radionuclide. Calculation of the percentage uptake is of additional diagnostic value.
在未麻醉的甲状腺功能正常（n = 13）和甲状腺功能亢进（n = 18）的猫中测定甲状腺99mTcO4-（高锝酸盐）摄取百分比。静脉注射放射性核素后60分钟观察到最大摄取量，甲状腺功能正常的猫的摄取量为剂量的0.3%至3.9%（中位数2.23%），甲状腺功能亢进的猫的摄取量为剂量的5.2%至23.9%（中位数14.8%）（P < 0.05）。在评估的任何时间段内，高锝酸盐摄取百分比均无重叠。结论是，99mTcO4(-)扫描观察甲状腺的最佳时间是静脉注射放射性核素后60分钟。摄取百分比的计算具有额外的诊断价值。
