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.
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 includes imaging that shows blood flow to your heart during the test. Some stress tests have you exercise on a treadmill or bike to elevate your heart rate.
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.
A nuclear stress test is a minimally invasive diagnostic imaging procedure evaluating perfusion of blood through coronary arteries.
A nuclear stress test is an imaging test that requires you to be injected with a small radioactive tracer that helps doctors determine how well your heart is functioning. The tracer will lose its radioactivity through natural decay in about a day or two.
A nuclear stress test combines imaging technology, small amounts of radioactive material, and an exercise stress test to diagnose and monitor heart problems. Your doctor may use a nuclear stress test to diagnose coronary artery disease and assess damage from a heart attack or other heart problems.
A nuclear stress test is used to identify and assess potential blockages inside the coronary arteries. The test shows the blood flow to the heart muscle when it is stressed by either exercise or a stress inducing medication and to determine what areas of the heart have decreased blood flow.
What Is a Nuclear Stress Test? A nuclear stress test — also known as nuclear cardiac imaging — measures blood flow to the heart at rest and after activity. A small amount of radioactive material is injected into your arm, and a special camera scans your heart.
A stress test can help show if surgery, such as a valve replacement or a heart transplant, might be a safe treatment. If an exercise stress test doesn't show the cause of symptoms, your provider may recommend a stress test with imaging.
