| thallium stress t. |
(for detection of coronary artery disease): stress is placed on the cardiovascular system by exercising the patient on a treadmill or bicycle ergometer and thallous chloride Tl-201 is injected intravenously when stress is maximal, just prior to exercise cessation. Immediate (stress) and delayed (redistribution) images are obtained with a gamma camera (see thallium-201 myocardial perfusion scintigraphy); then abnormalities of radionuclide distribution and redistribution are assessed, compared with electrocardiograms obtained during exercise, and used to diagnose areas of ischemia and coronary artery disease. In patients incapable of exercise, stress is induced by injection of dipyridamole or adenosine.
