Coronary CT angiography (CCTA) has benefited from major technological advancements over the past two decades, resulting in improved image acquisition and reconstruction techniques with better spatial and temporal resolution. However, image quality remains susceptible to motion-related artefacts when coronary artery movement exceeds the scanner’s temporal resolution. Imaging during mid-diastole at heart rates (HRs) <60 beats per minute (bpm) generally provides the most stable, motion-free pha…
