Assessment of Myocardial Viability With ^99m Tc Sestamibi in Patients Undergoing Cardiac Transplantation

Abstract

99mTc sestamibi scintigraphy can be used to accurately quantify the extent of myocardial scarring. Furthermore, the relative sestamibi activity in perfusion defects, measured several hours after administration, is a good indicator of myocardial viability determined with microscopy.
