Non-Invasive Assessment of Myocardial Viability - American ...

Aug 14, 2020  Being a potassium analog, thallium can be used to detect myocardial cell membrane integrity via Na/K ATPase channels, where viable cells demonstrate delayed uptake as compared to resting imaging. 10 Unlike thallium, technetium-based SPECT does not demonstrate a delayed distribution. 11 In the recent decades, thallium has rarely been used due to ...

Assessment of myocardial viability by nuclear imaging in ...

Feb 27, 2020  The myocardial uptake of thallium-201 is a sarcolemmal membrane Na/K ATPase-dependent active process requiring cell membrane integrity, and is therefore indicative of myocardial viability. Thallium-201 uptake by myocytes is also a reflection of regional perfusion (required for delivery of tracer to the myocyte) and viability.
