Thallium-201 is a monovalent cation, property similar to potassium. It has a half-life of 73 hours and emits 80 keV photons. Its peak myocardial concentration achieves in 5 minutes and has the property of rapid clearance from the intravascular compartment. The differential washout-clearance of thallium 201 is more rapid from normal myocardium.

Cardiac Stress Test | Cedars-Sinai

Cardiac Stress Test. You have been referred by your physician for a stress test — an exam which shows how well your heart works during physical activity. The exam can be used to measure the blood flow to the heart as well as to see any areas where the heart has been damaged (such as by a heart attack). The test measures blood flow to the ...

Myocardial perfusion scan

The test can also be known as a thallium scan, MIBI scan, technetium scan or nuclear medicine scan. ... The myocardial perfusion scan looks at how well your heart muscle is being supplied with blood. Your doctors may refer you for other tests if they think your coronary arteries are narrowing, as a stent or bypass operation may be recommended.

RACGP

Myocardial perfusion scans (MPS) are obtained after the intravenous (IV) injection of a small dose of radiotracer at rest and following physiological (exercise) or pharmacologic (adenosine, dipyridamole or dobutamine) stress. Originally, thallium was used but it has been superseded by the technetium-labelled synthetic compounds, sestamibi and ...

What Is a Thallium Cardiac Stress Test?

What Is the Thallium Stress Test in Cardiology? During a thallium scan, a radioactive tracer is used to measure the blood flow to various areas of the heart. These examinations are the more prevalent kind of nuclear medicine scans. These scans will help the doctor learn more about the cells in the heart and its blood supply.

Noninvasive Cardiovascular Imaging | UCI Health | Orange …

A thallium stress test—also called a myocardial perfusion scan—evaluates blocked or narrowed coronary arteries, blood circulation to cardiac structures and damaged or dead tissue in the heart muscle. The patient receives an injection of a small amount of 210- thallium or other radioisotope then tested during exercise and at rest.

MSI | Thallium Scan

A thallium scan is a test, usually performed with treadmill stress or a "drug" stressing agent, to see the blood supply to the muscle of your heart. Why do I need a thallium scan? Your doctor needs to know if your heart muscle is getting enough blood at rest and at exercise.

An isotope stress test is also known as a nuclear, thallium, Cardiololite, Myoview or dual isotope stress test, depending upon the method used. During exercise, healthy coronary arteries dilate (develop a more open channel) more than an artery that has a blockage.

Adenosine SPECT Thallium Imaging

Adenosine single-photon emission computed tomography (SPECT) thallium (Tl-201) imaging is a non-invasive myocardial perfusion imaging (MPI) test.

MUGA Scan | Cancer.Net

A MUGA scan uses a special camera to create computer-generated images of the beating heart. A small amount of a radioactive contrast medium or tracer, called technetium-99m-pertechnetate (Tc-99m), is injected into a vein. The tracer is like a dye. It binds to your red blood cells, which carry oxygen throughout your body.
