Title: Deposition of small 99mTc-labelled colloids in bone marrow and lymph nodes. Author: Nagai K, Ito Y, Otsuka N, Muranaka A. Journal: Eur J Nucl Med; 1982; 7(2):66-70. PubMed ID: 7084270. Abstract: The degree of deposition of small-particle colloids such as 99mTc-antimony sulfide colloids (ASC-group) and 99mTc-rhenium colloid (Tc-Re) in the bone marrow and lymph node was studied. H-ASC that was prepared in our laboratory was concentrated to a higher degree both in the bone marrow and lymph nodes, compared with other colloids. The H-ASC were mostly from 5 to 12.5 nm and the shape was uniform and spherical. The degree of deposition of Tc-Re in rabbit lymph nodes was not higher, however, the label was considered to be valuable clinically. The degree of deposition of Tc-Re in the bone marrow was not satisfactory. The size of Tc-Re was much smaller than H-ASC, ranging from 3 to 5 nm. From these results, it is considered that factors affecting deposition in the marrow are not identical to those in the lymph nodes.[Abstract] [Full Text] [Related] [New Search]
