Abstract

We evaluated the performance of a new volume computed tomographic (CT) scanner with regards to image quality and signal homogeneity.Twenty-four subjects were prospectively enrolled. Subjects had prior imaging with rate control. Quantitative analyses performed placing regions of interest in myocardium, blood pool, and aorta. Image quality and diagnostic interpretability were assessed using Likert scales.Median heart rate was 60 and 57 bpm for volume and 64-slice coronary CT angiography (P=.02). Improvement in homogeneity was demonstrated within myocardium (30% improvement), blood pool (73%), and aorta (73%). Improvement in image quality observed at per-patient/per-segment level.Pilot study confirmed improvements in signal homogeneity and diagnostic interpretability, despite imaging at higher heart rates.
