Myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) has widespread
clinical use because of its well-documented diagnostic accuracy for detecting coronary artery disease (CAD).
Cardiac SPECT imaging needs to become shorter and use lower radiation doses in order to compete with other available
noninvasive imaging modalities. Recently introduced cadmium zinc telluride (CZT) SPECT cameras have the potential to
achieve both of these goals. New SPECT CZT camera technology drastically reduces imaging time for patients while also
reducing their radiation exposure compared to previously used technologies, without any loss of image quality.
This article describes these innovations, which provide a strong foundation for the continued success of myocardial perfusion
