Unlike thallium, Tc-99m sestamibi (Cardiolite) does not undergo {{c1::redistribution}} and remains fixed in the myocardium.

Extra Info
Thallium undergoes redistribution with simultaneous cellular washout and re-extraction of blood-pool radiotracer. Only viable myocardium can extract thallium. Therefore, ischemic but viable myocardium will show perfusion defect during stress due to decreased blood flow, but normalization of defect on post-redistribution images. In contrast, an infarct or scar will show a persistent defect.
