Background: The evaluation of hospitalized patients with chest pain and non-diagnostic electrocardiogram is problematic and the optimal cost-effective strategy for their management controversial. Objectives: To determine the utility of myocardial perfusion imaging with thallium-201 for predicting outcome of hospitalized patients with chest pain and a normal or non-diagnostic ECG.

Non-Invasive Assessment of Myocardial Viability -

2020-8-14  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 ...

2016-12-21  The utility of planar thallium imaging was enhanced by the development of quantitative techniques for assessing the initial distribution and subsequent washout of thallium. Un-fortunately, planar imaging is inherently suboptimal for as-sessing myocardial perfusion because frequent overlap of normally and abnormally perfused myocardial regions ...
