Begin the stress imaging as soon as possible the injection. Do not wait no more than 5 - 10 minutes, as Thallium starts to redistribute. DO NOT FEED THE PATIENT UNTIL REST SCAN IS COMPLETE 3 hrs post stress injection perform a resting scan. Study Parameters: Protocol name - "ST STRESS THALLIUM" and "RT REST THALLIUM."

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. Thallium scans are also done after a bypass or angioplasty to evaluate the success of the procedure. Sometimes technetium is used instead of thallium as the radiopharmaceutical agent.

Can a stress test show a blockage? Stress tests can detect when arteries have 70% or more blockage. This severe narrowing is what causes the severe chest pain called angina. But normal results from a stress test do not rule out the possibility of a future heart attack. This is because a plaque can still rupture, form clots and block an artery.

The stress thallium test is a nuclear medicine procedure that is used to evaluate how the heart responds to stress. The test is performed by injecting a small amount of radioactive thallium into the bloodstream. Images are then taken of the heart while it is working (under stress) and after it has rested.

A patient is injected with pharmacological vasodilator (adenosine (140 mcg/kg/min continuous infusion for six minutes) or regadenoson (one dose of 0.4 mg injection)) and a Tl-201 radio-tracer. Stress cardiac images are then taken after 15 minutes with gamma cameras. Rest cardiac images are then taken after 2.5 to 4 hours with gamma cameras.

Abstract. Stress thallium-201 scanning proved to be a highly sensitive and specific screening procedure for myocardial ischemia in 52 consecutive cases with coronary arteriograms. Stress thallium-201 scanning was considerably more accurate and more specific than the exercise electrocardiogram (ECG) as evidenced by a sensitivity of 83% compared ...

Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air. Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production.

The thallium stress test shows the size of heart chambers if any heart muscle is damaged or defected due to a heart attack in the past. The thallium stress test also shows if a heart is pumping blood properly and checks whether all the coronary arteries are supplying blood to the heart. The test measures the ability of your body to take the stress.
