Cardiac computed tomography (CT) has evolved considerably over the past 2 decades, including marked advances in both hardware and software technology. Recent developments have ranged from scan acquisition and post-processing to image display and interpretation. A few examples of these advances include dual-source scanners, multidetector row systems with increasing numbers of detector elements, iterative reconstruction algorithms, faster workstations, expanded clinical capabilities such as estimating the functional significance on coronary stenoses and more recently, the use of photon-counting detectors. In parallel, large clinical trials have established the value of cardiac CT in various clinical scenarios, thus expanding the evidence base supporting cardiac CT use in multiple areas of clinical medicine. As a testament to this progress, cardiac CT is now recommended in numerous international guidelines for indications spanning from evaluation of coronary artery disease (CAD) to guiding structural heart disease interventions. Notwithstanding the substantial progress in technology, image quality remains an essential component for the use of cardiac CT in both clinical and research settings. Herein, we review important considerations for patient selection, patient preparation and imaging protocols for acquisition of high-quality cardiac CT images.
