Thallium Heart Scan: Definition A thallium heart scan is a test using a special camera and a small amount of radioactive substance injected into the bloodstream to make an image of the blood flow to the heart. Purpose A thallium heart scan is used to evaluate the blood supply to the heart muscle. It can identify areas of the heart that may ...

The present study should help define those diseases that are associated with increased lung uptake of thallium and alter this ratio. Moreover, just as thallium uptake by the lungs during exercise in CAD has been shown to be of prognostic value, this may prove to be similarly true in primary lung disease and serve as a useful tool to monitor ...

Explore the Library. Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through your heart muscle. It can show areas of the heart muscle that aren't getting enough blood flow. It can also show how well the heart muscle is pumping. This test is often called a nuclear stress test.

Mortality. There were 12 total deaths (2.6%) during follow-up in the entire population of 463 patients referred for MPI with interpretable baseline ECGs who achieved ≥10 METS of exercise workload. The annualized all-cause mortality rate was 1.2%. Of these, 12 (84.6%) were in the group reaching ≥85% of the MAPHR.

How the Test is Performed. This test is done at a medical center or health care provider's office. It is done in stages: You will have an intravenous (IV) line started. A radioactive substance, such as thallium or sestamibi, will be injected into one of your veins. You will lie down and wait for between 15 and 45 minutes.

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 …
