Abstract
Quantitative conjugate-view external counting techniques were applied to estimate the radiation dose to the liver, spleen and metaphyseal growth complexes (distal femur and proximal tibia) for 10 pediatric patients undergoing 67Ga scanning procedures. The effective half-life of 67Ga in these organs was .apprx. 78 h. The dose per unit of administered activity for the liver and spleen was between 0.3 and 4.0 rad/mCi (0.08-1.08 Gy/GBq [gray/gigabecquerel] and 0.5 and 7.0 rad/mCi (0.13-1.89 Gy/GBq), respectively. For the metaphyseal growth plates the range was 2.3-14.3 rad/mCi (0.62-3.86 Gy/GBq).This publication has 0 references indexed in Scilit:
