Next Generation Adaptive Coronary Motion Correction Reduces Coronary Motion Artifact

Introduction: Coronary CT angiography (CCTA) is useful for the detection and exclusion of obstructive coronary artery disease; however, its utility can be degraded by motion artifacts. A next generation of adaptive motion correction has been developed that tracks motion of all three major coronary vessels in three-dimensions. The purpose of this study is to quantitatively assess the diagnostic utility of a new coronary motion correction algorithm applied to n=50 consecutive CCTA exams with motion artifact.
