Clinical evaluation, cardiac biomarkers, exercise stress testing, and myocardial perfusion imaging (MPI) are all vital components of the diagnosis or exclusion of coronary artery disease as the etiology of chest pain. Recent advances in single photon emission computed tomography (SPECT) camera technology and changes to the imaging protocols have allowed MPI to become a more efficient way of providing diagnostic information. Compared with conventional SPECT, new high-efficiency cameras provide increased sensitivity, energy and spatial resolution. This article reviews the current status.
