Positron emission tomography (PET) offers a unique, noninvasive method to study heart blood flow and metabolism. Cardiac PET is invaluable for diagnosing coronary artery disease and assessing myocardial viability.

Area of Science:

  • Cardiovascular Imaging
  • Nuclear Medicine
  • Medical Diagnostics

Background:

  • Positron emission tomography (PET) is a quantitative imaging technique for noninvasive cardiac assessment.
  • PET enables the study of normal heart function and disease-related alterations in blood flow and metabolism.
  • The technique has demonstrated efficacy in evaluating interventional therapies for heart conditions.

Purpose of the Study:

  • To highlight the unique capabilities of cardiac PET in clinical and research settings.
  • To emphasize PET's role in diagnosing coronary artery disease (CAD) and assessing myocardial viability.
  • To discuss the application of PET imaging in understanding cardiac physiology and pathology.

Main Methods:

  • Utilizes positron-emitting radioisotopes to label physiologically relevant substances.
