Abstract

The field of nuclear cardiology is witnessing a rapid growth in the installed base of hybrid SPECT/CT and PET/CT scanners. Although the CT component in the original hybrid SPECT/CT scanners was conceived only as a tool for performing attenuation correction (AC), this is now rapidly evolving into a multi-detector CT configuration that allows acquisition of diagnostic anatomic information including coronary calcium scoring (CCS) and coronary CT angiography (CCTA). A similar evolution has occurred with PET/CT devices. Original scanners were designed only for oncologic imaging and fitted with single- or two-slice CT scanners.1 However, this has evolved very rapidly, and 16-slice or higher CT configuration is common across all manufacturers.
