Detailed explanation-1: -Technetium 99m sestamibi (MIBI), also known as 99m Tc-methoxy isobutyl isonitrile, is a radiopharmaceutical used to evaluate pathology within the cardiac, breast, and parathyroid tissues. Sestamibi is part of the radioactive diagnostic agents class of medications, characterized as a lipophilic cationic radiotracer.
