Quantitative conjugate view external counting techniques were applied to determine radiation dose to the liver and spleen in pediatric patients undergoing 99mTc-sulfur colloid (Tc-SC) liver scans. The effective half-life of 99mTc-SC was 5.8 +/- 0.23 hours and 5.2 +/- 0.68 hours in the liver and spleen, respectively. Dose per administered activity ranged from 0.34 to 0.63 rad/mCi (92 to 170 muGy/MBq) for the liver and 0.35 to 1.96 rad/mCi (95.0 to 530.0 muGy/MBq) for the spleen. The spleen to liver dose ratio ranged from 1.0 to 4.9. These values are compared with results extrapolated from published adult data to the pediatric population.
采用定量共轭视图外部计数技术来测定接受99m锝-硫胶体（Tc-SC）肝脏扫描的儿科患者肝脏和脾脏的辐射剂量。99mTc-SC在肝脏和脾脏中的有效半衰期分别为5.8±0.23小时和5.2±0.68小时。肝脏每给予活度的剂量范围为0.34至0.63拉德/毫居里（92至170微戈瑞/兆贝可），脾脏为0.35至1.96拉德/毫居里（95.0至530.0微戈瑞/兆贝可）。脾脏与肝脏的剂量比范围为1.0至4.9。将这些值与从已发表的成人数据外推至儿科人群的结果进行比较。
