PET Cardiac Scan

PET/CT imaging provides a way to assess the severity of heart disease and measure its impact on heart function. Clinical studies show an important role for PET/CT in screening for coronary heart disease, assessing flow rates and flow reserves, and distinguishing viable from nonviable heart tissue.

Two areas of clinical application have emerged:

  • Myocardial Perfusion: PET/CT is used by physicians to reveal whether or not a patient has coronary artery disease, which is caused by accumulation of plaques within the walls of the arteries that supply blood to the heart.
  • Myocardial Viability: PET/CT is used by physicians to determine the viability of heart muscle and if it has been permanently damaged due to decreased or absent blood flow.
