How does thallium viability work
WebFeb 1, 2024 · 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.

WebMar 21, 2024 · The benefit of assessing myocardial viability before surgery in patients with LV dysfunction has been shown with a number of different imaging modalities, including dobutamine echocardiography, myocardial perfusion scintigraphy with thallium and technetium agents, and PET. WebThe normal amount of thallium in human urine amounts to less than 1 ppm and 5-10 ppb in human hair. Although thallium can be measured in blood, this tissue is not a good indicator of exposure since thallium stays there too short a time. We do not know yet whether thallium levels measured in the body can be used to predict possible health effects.
