Abstract

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.

摘要

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。
