Abstract
Coronary artery disease (CAD) is the leading cause of death in the United States (1). Myocardial perfusion imaging (MPI), using single photon emission computed tomography (SPECT) is one of the most frequently used diagnostic tools for patients at risk for CAD, and has significant prognostic value (2). Dedicated cardiac SPECT cameras such as the D-SPECT have been specifically designed for MPI studies. Equipped with new technology, the D-SPECT camera has demonstrated superior image quality when compared to standard SPECT or SPECT/CT cameras, while reducing patient and personnel radiation exposure and decreased imaging time (3). In this continuing education article focuses on the specifications of both SPECT/CT and D-SPECT camera systems, radiopharmaceutical dosing requirements, imaging workflows and some disadvantages of utilizing each camera system.
