The in vitro viability, chemotaxis, and labeling stability of leukocytes labeled using ^sup 99m^Tc-exametazime stabilized with methylene blue were evaluated and compared with those obtained using nonstabilized ^sup 99m^Tc-exametazime. Methods: Two identical leukocyte populations, from 30 healthy donors, were labeled simultaneously using freshly prepared and 2-h-old stabilized ^sup 99m^Tc-exametazime. The following quality control techniques were performed on each labeled leukocyte sample: eos...
