Count density curves for gated SPECT myocardial perfusion imaging studies: An overview of technical considerations, patterns in various arrhythmia-related artifacts, and a technologist’s guide for curve plotting

Gated SPECT myocardial perfusion imaging (MPI) is among the most widely used diagnostic procedures in nuclear medicine. Complexity of the acquisition procedure and its dependence on the status and regularity of the patient’s electrocardiographic signal during image acquisition make this procedure susceptible to technical errors and a variety of artifacts. Thus, a number of tools have been developed to control the quality of images. A qualified technologist or physician should have a substantial knowledge of various artifacts and be familiar with using the available state-of-the-art software packages for advanced processing and appropriate quality control tools, including count density curves, and how to plot them. In the present technical note, we intended to provide an overview of technical considerations regarding some of the most important arrhythmia-related artifacts in gated SPECT MPI and available quality control tools, primarily focused on count density curves, and...
