Albumin particles are used in nuclear medicine as carriers of diagnostic and therapeutic radionuclides. Temperature was used to prepare these particles. After size determination, the particles were marked with gamma-irradiated radionuclide 99mTc in the presence of stannous chloride as a reducing agent. Chromatography methods analyzed radiochemical purity. For labeled particles, stability in normal saline and biodistribution in normal and glioma tumorized rats were investigated. The size of particles was determined below 50 nm. Radiochemical purity of more than 98% was obtained. Evaluation of labeled particle stability showed radiochemical purity of more than 90% during 6 hr in saline and human serum solutions. Biodistribution studies revealed liver and tumor uptake followed by high kidney washout. Gamma imaging scintigraphy in rats showed tumors and kidneys. The results confirmed the ability of marked particles as a tumor diagnostic radiopharmaceutical.
