초록

낮은 방사능의 $^{99m}$ Mo으로부터 methyl ethyl ketone으로 추출하여 제조된 Na $^{99m}$ TcO$_4$를 가지고 폐검진에 사용되고 있는 $^{99m}$ Tc Ferric Hydroxide Macroaggregates를 제조하였으며 여러 pH 범위에서 입자의 크기와 수가 변하는 모양을 검토하였고 pH 6-7에서 평균입자의 크기가 scanning에 가장 적당한 20~60$\mu$이었다. 토끼와 인체에 주사하여 좋은 곁과를 얻었다.

$^{99m}$Tc Ferric Hydroxide Macroaggregates for Lung Perfusion Studies were prepared from home made Na $^{99m}$TcO$_4$ which was extracted by methyl ethyl ketone from low activity $^{99m}$Mo. Particle size was in between 20 and 60$\mu$. Rabbit and human body tests gave excellent results.sults.
