7 Ιαν 2023 · If you have coronary artery disease, a nuclear stress test can help your health care provider learn your risk of a heart attack or other heart event. The test uses a positron emission technology (PET) scanner or single-photon emission computed tomography (SPECT) scanner.
18 Αυγ 2023 · 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. There are two types of MPI: single photon emission computed tomography (SPECT) and positron emission tomography (PET).
24 Απρ 2023 · While stress testing can be performed in a variety of ways, more commonly performed and widely available are exercise electrocardiography (EKG) and exercise or pharmacological stress testing along with imaging such as echocardiography or radionuclide myocardial perfusion imaging (rMPI).
31 Μαΐ 2022 · A nuclear cardiac stress test helps diagnose and monitor heart problems such as coronary artery disease. A healthcare provider connects you to an EKG machine, injects a tracer into your bloodstream and takes images of blood flow to your heart before and after exercise.
A nuclear stress test uses a gamma camera to image radioisotopes injected into the bloodstream. The best known example is myocardial perfusion imaging. Typically, a radiotracer (Tc-99 sestamibi, Myoview or thallous chloride 201) may be injected during the test.
28 Μαΐ 2024 · A nuclear stress test is different than a regular stress test. A regular stress test uses an ECG to record your heart rate and rhythm, while a nuclear stress test captures images of your heart. The nuclear stress test uses a radioactive tracer to make a picture.
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.
