1 Σεπ 2022 · A main objective of stress testing is to assess the functional or physiological consequences of anatomic coronary artery disease (CAD). The traditional gold standard test for the diagnosis of CAD is invasive coronary angiography via cardiac catheterization.

7 Ιαν 2023 · A nuclear stress test is an imaging test that shows how blood goes to the heart at rest and during exercise. It uses a small amount of radioactive material, called a tracer or radiotracer. The substance is given by IV.
1 Σεπ 2021 · It differs from stress testing in that it directly visualizes the coronary arteries and can quantify the degree of stenosis and assess plaque characteristics . In contrast, stress testing assesses LV wall-motion abnormalities or perfusion defects to determine if obstructive CAD is present.
A thallium (or cardiolite) scan uses a radioactive tracer to see how much blood is reaching different parts of your heart. These tests are the more common forms of tests called nuclear medicine scans. You may also hear them called: thallium myocardial imaging. cold spot imaging.
24 Απρ 2023 · Half-lives of PET tracers are short; hence pharmacological stress testing with vasodilators is preferred than exercise stress testing. When the radioactive tracer is administered intravenously, it allows visual assessment of coronary blood flow and perfusion to the cardiac muscles.
10 Μαρ 2023 · A thallium stress test is different from an exercise stress test, which only uses electrodes connected to an EKG to record your heart’s electrical activity as you exercise.
18 Αυγ 2023 · 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.
