BONE SEEKING TECHNETIUM 99M COMPLEX

摘要

A technetium-99m-stannous-phosphate complex in which the phosphate moiety includes pyrophosphate and in which no more than 5 to 15% or 20% by weight of such phosphate moiety is a linear polyphosphate of molecular weight greater than pyrophosphate, a method of making the same, a method of using the same by in vivo intravenous administration to a mammal of the sterile, nonpyrogenic complex followed by radioassay scanning or imaging the skeletal structure, and a kit made up of a stannour-phos-phate complex in which the phosphate moiety is pyrophosphate and in which no more than 5 to 15% or 20% by weight of such phosphate moiety is a linear polyphosphate of molecular weight greater than pyrophosphate.
