^sup 99m^Tc-Sestamibi is commonly used for mammoscintigraphy. Occasional uptake of ^sup 99m^Tc-exametazime in various tumors has been described. In this study, an intraindividual comparison of these 2 radiopharmaceuticals for mammoscintigraphy was made. Methods: A kinetic study (30 min) in the lateral prone view of 20 breast tumors (≥1 cm) in 20 women was conducted with ^sup 99m^Tc-exametazime. Thereafter, 21 breast tumors (≥1 cm) in 21 women were examined with both agents (2 patients were included in both groups) under identical conditions (interval, 2-7 d). In the latter group, the tumor-to-background breast activity ratio and the tumor uptake normalized to the administered ...
