Abstract
BackgroundTo determine the effect of a novel intracycle motion correction algorithm (MCA) on diagnostic accuracy of coronary computed tomographic angiography.MethodsCoronary artery phantom models were scanned at static and heart rate (HR) simulation of 60–100 beat/min and reconstructed with a conventional algorithm and MCA.ResultsAmong 144 coronary segments, improvements in image interpretability, quality, and diagnostic accuracy by MCA were observed for HRs of 80 and 100 (P< .05 for all), but not for HR of 60.ConclusionNovel intracycle MCA demonstrates improved HR-dependent image interpretability, and quality and accuracy, particularly at higher HRs.
