A thallium stress test is a type of nuclear scanning test or myocardial perfusion imaging test. It shows how well blood flows to the heart muscle. The test is usually done along with an exercise stress test on a treadmill or bicycle. When a patient reaches his or her maximum level of exercise, a small amount of radioactive substance called thallium is injected into the bloodstream. It shows where the heart muscle is not getting a normal blood supply.
What else can I help you with?
What test measures the flow of blood through the heart during activity is evaluated by injecting thallium into the bloodstream?
The test you are referring to is called a thallium stress test. This test helps evaluate the blood flow to the heart during physical activity by using a radioactive form of thallium injected into the bloodstream. It can help identify areas of reduced blood flow in the heart muscle, indicating possible blockages in the coronary arteries.
What is a persantine thallium study?
A persantine thallium study, also known as a cardiolite stress test, is a diagnostic imaging test used to assess blood flow to the heart muscle. It involves injecting a radioactive substance called thallium or a similar agent while the heart is at rest and then again while it is stressed with medication like persantine. Images are taken to assess blood flow abnormalities, which can indicate coronary artery disease.
Should someone with atrial fibrillation have a exercise stress test or a thallium stress test?
If you are a patient currently in atrial fibrillation. Generally speaking an adenosine or lexiscan nuclear stress tests are usually the best options. The other medicated stress test is Dobutamine (both echocardiogram and Nuclear). You do not want to use Dobutamine on patients at risk to go into atrial fibrillation because it is a drug that can induce it. For patients that are in chronic atrial fibrillation dobutamine can be used but is not considered to be as diagnostic as a lexiscan or adenosine stress test. The reason being (and this goes or exercise stress tests as well) dobutamine is a heart rate dependent test. This means the closer the heart rate gets to the patients age predicted max HR the more accurate the test is at detecting heart disease. The assumption in this is that the patient is in a sinus rhythm. Myocardial oxygen demand correlates directly with patients HR when the patient is in sinus rhythm. If the patient is in atrial fibrillation that correlation with myocardial oxygen demand becomes much more cloudy thus reducing the sensitivity of an exercise or dobutamine stress test with patients in atrial fibrillation. Both lexiscan and adenosine eliminate HR demands in detecting CAD which makes them the best test for a.fib patients.
Which isotope of thorium is used for stress tests?
Thorium-232 is used for stress tests in the form of Thallous chloride (thallium chloride). It is a nuclear reaction that helps make images of the heart muscle and blood flow to reveal any blockages or abnormalities.
How long does thallium stay in the body after a stress test?
In my case, the effects lasted for approximately 90 days. Although the actual "medicine" may have left my body, the effects of it stayed. My blood pressue was high, I was lathargic and had on and off feelings that I could have a heart attack at any moment. I also had feelings of depression. If you know your arteries are "clogged", there is no reason to have the stress test done. (my opinion only) Have an angiography. That way, they can possibly open the clog when its discovered. Be prepared though, they may have to do immediate "BY Pass surgery....
What stress test involves the use of radiopharmaceutical?
Thallium is the most common radiopharmaceutical used in nuclear medicine cardiac stress tests. Thallium shows how well blood travels through the heart in an active or stressful environment.
What diagnostic procedure involves the use of a radiopharmaceutical?
thallium stress test

It can help identify areas of reduced blood flow in the heart muscle, indicating possible blockages in the coronary arteries.
Which diagnostic procedure uses a radiopharmaceutical to assess the patient's heart function?
thallium test
What care should a patient receive after a thallium heart scan?
The thallium scan is performed in conjunction with an exercise stress test. At the end of the stress test (once the patient has reached the highest level of exercise he or she can comfortably achieve), a small amount of the harmless radioisotope.
What is a persantine thallium study?

Does Medicare pay for routine heart stress test?
Medicare will pay 80% as long as it is as an out-patient test.
What test's the flow of blood through the heart during activ ity is evaluated through the use of a radionuclide?
A nuclear stress test is typically used to evaluate the flow of blood through the heart during activity using a radionuclide tracer. This test helps to identify any blockages or abnormalities in the blood flow to the heart muscle.
What does a clinical correlation mean from a stress test?
A clinical correlation from a stress test involves interpreting the test results in conjunction with the patient's symptoms, medical history, and other diagnostic tests to arrive at a diagnosis or treatment plan. It helps the healthcare provider determine the significance of abnormal findings on the stress test in relation to the patient's overall health condition.
What is made of thallium?
Thallium is used in a variety of applications, such as in the manufacturing of electronic components, infrared optics, and catalysts. It is also used in some specialized medical procedures, like nuclear medicine for diagnosing heart disease. Additionally, thallium compounds have historically been used in rat poisons and insecticides.
What is the medical term meaning evaluation of heart fitness by having patient exercise on a treadmill?
You have described a cardiac stress test.
