| Research Abstract |
Increased permeability of blood vessels in diseased bone suggested that ^<99m>Tc-labeled compound of higher molecular size and hydroxyapatite binding would be useful to detect the diseased bone. Since ^<99m>Tc-labeled oligo-aspartic acid showed higher molecular size and higher hydroxyapatite binding than those of ^<99m>Tc-methylenediphosphonate (^<99m>Tc-MDP), to evaluate the molecular design of ^<999m>Tc-labeled oligo-aspartic acid, the accumulation of ^<99m>Tc-labeled oligo-aspartic acid in bone metastatic tumor of rat was compared with ^<99m>Tc-MDP. The tumor to normal region ratios of ^<99m>Tc-labeled oligo-aspartic acids were higher than those of ^<99m>Tc-MDP. These results suggested that the present molecular design would be useful to image bone metastatic tumor.
