Preparation, analysis and application of [99mTc]Human Albumin Microspheres ([99mTc]HAM) for lung scanning.

Kits were developed for the sterile labelling of Human Albumin Microspheres with 99mTc. The microspheres were prepared, sieved to get the desired particle size and autoclaved for sterilization. The spheres were treated with stannous chloride and the pH of the suspension was adjusted to 3.

A new technique for the preparation of ready-to-use macroaggregated albumin (MAA) kits to be labelled with 99mTc for lung scanning.

Kits were developed for the sterile labelling of macroaggregated albumin (human) with 99mTc. 0.4 mL of 20% HSA, 1 mL of SnCl2 X 2H2O containing 5 mg and 1.
