PMID: 7562061 Abstract Several 99mTc-labeled radiopharmaceuticals have been developed for lymphoscintigraphy of the extremities. In the United States, however, these agents are not widely used clinically. This study evaluates the use of smaller particle sizes ( < 0.1 micron) of 99mTc-sulfur colloid (99mTc-SC) for lymphoscintigraphy.

Antimony

Antimony (Sb; CASRN ) is a semimetal element with chemical properties similar to lead, arsenic, and bismuth. In nature, it is found associated with sulfur as stibnite. Antimony is used in white metal, a group of alloys having relatively low melting points. White metal usually contains tin, lead, or antimony as the chief component.
