概要

In this article, in the first part we discussed about basic point of ^<111>In-DTPA, and in the second part described two cases, in each case we used both ^<169>Yb-DTPA and ^<111>In-DTPA. ^<111>In-DTPA had chemical property of weak acidity (pH 6.0〜6.5) and was stable in human bodies because of good chelating nature. Effective half life of ^<111>In-DTPA was 16 hours, i.e. 6 hours shorter than that of ^<169>Yb-DTPA. It seemed to be slightly longer than that which had been rported. Imaging by using ^<111>In-DTPA and ^<169>Yb-DeTPA were almost the same, though there was a month of duration between the use of two pharmaceuticals. So we concluded that interpretative criteria of ^<169>Yb-DTPA cisternography could be applied to ^<111>In-DTPA cisternography.
