title: Radioactive tracers and the heart.
abstract: The most widely used tracer for the study of the heart muscle is thallium-201. The principal advantage of radioactive tracers in the study of the heart is that they tell us about regional as well as a overall function. In some cases a regional abnormality may be detected before the overall function of the heart is impaired.
