Nuclear (Cardiolite) / Exercise Thallium


This test is used to diagnose coronary heart disease. A radioactive substance called Thallium or Cardiolite is injected to the blood stream via a vein in your arm while walking on a treadmill. The thallium travels through the bloodstream giving off a small amount of radiation to the coronary arteries. The radiation is detected with computer images, which show the distribution of the substance in the heart. Preparation is minimal. The physician may ask you to go without eating two hours prior to the test.
