Technical Aspects of Cardiac PET Imaging and Recent Advances

As the number of myocardial perfusion single emission photon computed tomography studies performed in the United States has steadily declined over the past several years, an opposite trend can be seen for myocardial perfusion PET. This review covers basic technical aspects of cardiac PET imaging and recent advances that maximize the quality and efficiency of cardiac PET. The covered topics include radioisotopes used in cardiac PET and basics of acquisition and reconstruction, including time-of-flight techniques, PET detectors, attenuation correction, and respiratory gating techniques.
