| What Is Cardiac
Perfusion Imaging?
Cardiac perfusion imaging is a medical
test that uses a radioactive subtance,  known
as a tracer, to assess the flow
of blood to the heart muscle. It allows images
to be taken of the heart muscle during periods of
exercise (or stress) and rest.
(Other terms often used to describe
cardiac perfusion imaging include: myocardial perfusion
scan, cardiac nuclear imaging, and radionuclide stress
test. Based on the specific tracer that's used, it may
also be called Thallium, Cardiolite, or Myoview scan.)
