The term “nuclear” is used because a small amount of a radionuclide is injected in the patient during the test.
A radionuclide (thallium, technetium or sestamibi) is a radioactive substance that is employed as a tracer.
Cardiac nuclear medicine is useful in diagnosing and assessing coronary artery disease.
It is also used to evaluate cardiomyopathy and identify possible damage to the heart from chemotherapy or radiotherapy.
At this time, you will be given another injection of tracer and walk a few more minutes.
Depending on the type of nuclear medicine exam, the radiotracer is either injected into the body, swallowed or inhaled as a gas and eventually accumulates in the organ or area of the body being examined.
