    A:Exercise Thallium Scan is an investigation which is more accurate than a plain exercise test (TMT) in determining the presence of any severe blockages in the heart arteries. It is performed like an exercise test, but during exercise a radioactive material called Thallium is given by injection and a special gamma camera scans the heart.

  • Nuclear Thallium Stress Test

    Sometimes called a "Thallium scan" or "nuclear scintigraphy", this stress test is similar to an echo stress test, but it focuses in more on the coronary arteries and their ability to deliver blood to the heart under stress.A Thallium stress test may be indicated if the echo stress test was inconclusive, or it may be done instead, if there is a likelihood of coronary artery disease.
