- Answer: A nuclear stress test, what we call myocardial perfusion imaging is a test that looks at the blood flow to your heart muscle. We do that while you're resting and also with some form of stress, either exercise or sometimes we give a medicine to simulate the effects of exercise.

What Is A Nuclear Stress Test? Question: What is a nuclear stress test (Myocardial Perfusion Imaging), and how does it differ from either a medicine or exercise stress Test? Answer: A nuclear stress test, what we call myocardial perfusion imaging is a test that looks at the blood flow to your heart muscle. We do that while you're resting and also with some form of stress, either exercise or sometimes we give a medicine to simulate the effects of exercise. The analogy here would essentially be looking at the blood flow to your heart the way that gas flows to a car engine.

Nuclear Stress Test Images taken at rest (left) and during exercise (right) from a nuclear stress test. 1  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 Test Cost Nuclear Stress Test Cost. A nuclear stress test consists of a treadmill stress test and imaging tests. Before the imaging procedures, a radioactive dye is administered intravenously. Thereafter, a special camera is used to observe the blood flow to the heart during rest and physical exertion.

- A nuclear stress test done with thallium will average 25 mSv of radiation. A test done with technetium-sestamibi will be around 12 mSv. For comparison, the average person receives about 3 mSv / yr of radiation from natural sources. The lifetime risk of cancer is about 0.004% per mSv or about 0.1% per thallium scan.

Nuclear stress test: What does it involve? The nuclear stress test can help to diagnose a heart condition by giving vital information. This data includes: The size of the heart chambers. How well the heart is pumping blood. Whether there is any damage to the heart. If there is any blockage or narrowing of the coronary arteries that provide blood to 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 Testing: What You Need To Know Like other stress tests, the nuclear stress test involves obtaining two sets of images of the heart muscle, one at rest and one while, or immediately after, exercise. This will give the doctor two images to compare to evaluate how well the heart works under stress.ike other stress tests, the nuclear stress test involves obtaining two sets of images of the heart muscle, one at rest and one while, or immediately after, exercise. This will give the doctor two images to compare to evaluate how well the heart works under stress.

Stress Testing/Stress Echocardiogram The purpose of a non-exercise cardiac nuclear stress test is to assess the blood flow to the heart muscle at peak stress and again at rest. This test is used for patients who are unable to exercise on a treadmill. The medication Lexiscan is given, which acts to dilate the coronary arteries.

What is a thallium stress test? A thallium stress test is a nuclear imaging test that shows how well blood flows into your heart while you’re exercising or at rest. This test is also called a cardiac or nuclear stress test. During the procedure, a liquid with a small amount of radioactivity called a radioisotope is administered into one of your veins.

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.

Chemical Stress Test Doctors may call for the following heart stress tests: MRI, echocardiogram, and nuclear imaging. In a nuclear stress test, radioisotopes are introduced into the patient. Doctors can then study images taken of the heart during rest and stress. Several types of chemical stress tests for the heart are recommended. The chemical stress test procedures are as follows: Nuclear medicineand myocardial perfusions scans known as PET scan-positron emission tomography. Drugs to regulate heart rate and blood flow.
