Positron Emission Tomography
A stress PET examination can reliably demonstrate myocardial blood flow using Rubidium-82 (Rb-82) or Nitrogen-13 (N-13) ammonia.
Limited data are available for PET perfusion studies in the setting of acute chest pain, although there is growing evidence for diagnostic and prognostic applications in chronic coronary disease .
PET can also document anaerobic metabolism using fluorine-18-2-fluoro-2-deoxy-D-glucose and other metabolic tracers. This technology is not universally available and, therefore, is less well studied in the workup of the acute chest pain patient .
