What is a Nuclear Stress Test? A nuclear stress test is a test that shows your doctor how well the blood flows to your heart during physical exertion. A nuclear stress test is a test that shows your doctor how well the blood flows to your heart during physical exertion. During a nuclear stress test, you'll be injected with a radioactive dye, and a scanner will take pictures of your heart. Then you'll be asked to walk or run on a treadmill or pedal on a stationary bicycle while some tests are being done on your heart.

- By Mayo Clinic Staff. A nuclear stress test measures blood flow to your heart at rest and while your heart is working harder as a result of exertion or medication. The test provides images that can show areas of low blood flow through the heart and damaged heart muscle. The test usually involves taking two sets of images of your heart — one while you're at rest and another after you heart is stressed, either by exercise or medication.

- |. Share. A nuclear stress test lets doctors see pictures of your heart while you are resting and after you have exercised. The test can show the size of the heart's chambers, how well the heart is pumping blood, and whether the heart has any damaged or dead muscle. Nuclear stress tests can also give doctors information about your arteries and whether they might be narrowed or blocked because of coronary artery disease.

Nuclear Stress Test What will happen during the test? During a nuclear stress test, first you will be injected with Cardiolite, a radioactive tracer, in the vein of your arm or hand. Cardiolite is taken up by the heart muscle through the coronary arteries in proportion to the blood flow to it.

Nuclear Pharmacological Cardiac Stress Test The objective of a pharmacological nuclear stress test is to simulate exercise in order to raise heart rate and essentially stress the heart. Instead of using a treadmill it is accomplished by injecting a medication that causes some blood vessels in the heart to open (dilate) just as would occur if you were exercising.

What Is A Nuclear Stress Test? So that's what the nuclear stress test does. And it's very helpful, not only in diagnosing individuals who may have coronary disease, but also in patients who have known coronary disease at giving us information regarding how severe it is and what the prognosis is as well.

- A nuclear stress test is similar to the exercise stress test or pharmacological (chemical) stress test, but a small amount of radioactive substance is used to determine the health of the heart and blood flow to the heart.he nuclear stress test can be referred to by other names, such as a thallium stress test 1, myocardial perfusion scan 2, or radionuclide test 3.

Overview By Mayo Clinic Staff. Your doctor will discuss the results of your nuclear stress test with you. Your results could show: Normal blood flow during exercise and rest. You may not need further tests. Normal blood flow during rest, but not during exercise.

Cardiac Nuclear Exercise Stress Test The test is done in two parts, resting and stress. The first part is done after an intravenous (IV) is started in your arm and the nuclear imaging material is injected into your vein. This will be allowed to circulate for 30 minutes while you rest comfortably on a bed or in a chair.

- What is a pharmacological nuclear stress test? A pharmacological nuclear stress test is a diagnostic test used to evaluate blood flow to the heart. During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer images of the heart.

Nuclear Stress Test Cost Basically, this test comprises a treadmill test, and tests wherein the images of heart are observed at rest and after physical activity. A nuclear stress test can be expensive. On an average, this test costs around USD 2,000. At times, the cost could go up to USD 5,000. Basically, the high cost can be attributed to the expensive medical equipment that is required for this imaging procedure. Also, there are others aspects that contribute to the overall cost of the test.

Nuclear stress test In an exercise stress test, electrodes are taped to your chest to detect your heart's rhythm. A nurse or technician will watch your heartbeat on a monitor while you exercise. If your doctor orders a nuclear stress test, you'll also receive a shot of radioactive dye that shows the blood flow to your heart muscle.

What is a thallium stress test? A thallium stress test is a nuclear imaging test that shows how well blood flows into the heart while you’re exercising or at rest. This test is also called a cardiac or nuclear stress test. During the procedure, a radioisotope (nuclear liquid) is administered through an IV.

Medical Definition of Radionuclide stress test Medical Definition of Radionuclide stress test. Radionuclide stress test: A procedure that involves injecting a radioactive isotope, typically thallium or cardiolyte, into the patient's vein after which an image of the patient's heart becomes visible with a special camera. The radioactive isotopes are absorbed by the normal heart muscle.

- Cardiac nuclear stress tests can diagnose heart problems that other stress tests or an examination at rest might not detect. The drugs are approved for use during cardiac nuclear stress tests in patients who cannot exercise. The drugs dilate the arteries of the heart and increase blood flow to help reveal blockages or obstructions in the heart's arteries, the FDA explained.

Definitions &Translations Nuclear sclerosis. Nuclear sclerosis. Nuclear sclerosis is an age-related change in the density of the crystalline lens nucleus that occurs in all older animals. It is caused by compression of older lens fibers in the nucleus by new fiber formation. The denser construction of the nucleus causes it to scatter light.
