Step and shoot coronary CT angiography using 256-slice CT: effect of heart rate and heart rate variability on image quality

Objective To evaluate the effect of heart rate variability (HRV) and heart rate (HR) on intra-image “motion” and inter-image “stairstep” artefacts in step-and-shoot coronary CT angiography (CCTA) using a wide detector CT scanner. Methods 66 patients underwent step-and-shoot CCTA using 256-slice CT....
