Cardiac stress test Wikipedia

Nuclear stress test. The best known example of a nuclear stress test is myocardial perfusion imaging. Typically, a radiotracer (Tc99 sestamibi, Myoview or thallous chloride 201) may be injected during the test. After a suitable waiting period to ensure proper distribution of the radiotracer, scans are acquired with a gamma camera to capture ...

even in the absence of myocardial perfusion defects (17). CONCLUSION Thallium was the first widely available radiopharmaceutical for myocardial perfusion scans. Since the late 1970s, 201Tl was used with planar imaging to detect coronary artery disease. In the 1980s, 201Tl was the most common radiopharmaceutical used in SPECT myocardial perfusion

Jul 30, 2015· Myocardial perfusion imaging (MPI) is a noninvasive imaging test that shows how well blood flows through (perfuses) your heart muscle. It can show areas of the heart muscle that aren’t getting enough blood flow. This test is often called a nuclear stress test. It can also show how well the heart muscle is pumping.
