✦ Synopsis
With 9 kinds of available 99mTc-colloid kits for RES imaging, especially from the aspect of RES imaging of the bone marrow, observations were conducted on pH, the presence of free 99mTc04, labelling efficiency, rabbit blood clearance, the uptake in RES, urinary excretion, as well as the scintigraphy with rabbits and clinical cases. Compared to 198Au-colloid, marrow to liver ratio was found to be about the same, but its uptake to the spleen and liver was greater. In particular its urinary excretion was much more marked than 198Au-colloid, and in clinical use the bladder was more often delineated. This fact seems to suggest that it is desirable to develope a 99mTc-colloid more suitable for the bone marrow scintigraphy.
