Using the amount of radiation received by one chest xray as 1, the dose received during one Thallium stress test is 590. Most nuclear stress tests involve 2 components, rest and exercise, and use a different isotope with a total exposure of The latter test is usually more definitive except for certain specific situations when Thallium is preferred.

The radioactive isotope thallium 201 behaves physiologically as a potassium analog, and when injected intravenously accumulates rapidly within the cells of many organs. Uptake of the isotope reflects both regional perfusion and sodiumpotassium pump activity. The radionuclide emits 80 keV xrays ...

A thallium stress test is a test given after you have either been given an exercise test on a treadmill or bicycle or if you are too sick for that then given a drug to mimic the blood flow that this exercise would entail. Then the thallium is given you and xrays are taken to see where the thallium can be found and in what concentrations.

Thallium201 (201 Tl) is the conventional perfusion tracer [4]. 201 Tl behaves like a potassium analog and enters the myocytes through Na + /K + ATPase channels. 201 Tl is injected intravenously at peak exercise or during pharmacological stress and imaging is started soon after completion of stress. Myocardial segments perfused by narrowed ...

Sep 10, 2009· The stress thal is a combination of the exercise or dobutamine stress test followed by the injection of a nuclear tracer (thallium99) to measure cardiac blood flow. The patient reaches the point of max stress (either exercise ro dobuta induced), gets the thallium injection and has images taken with the gamma camera to show perfusion.
