This study sought to evaluate the clinical feasibility, image quality and diagnostic accuracy of a prototype 3T post-contrast high-resolution whole-heart coronary MR angiography (CMRA) sequence with image-navigator (iNAV) based motion correction and 100% respiratory scan efficiency integrated into clinical cardiac MR scan before LGE imaging. The results showed CMRA imaging completed on average in 5.2minutes with promising image quality. CMRA showed good inter-modality agreement compared to computed tomography angiography (CTA) and high negative predictive value (NPV), which allows effective exclusion of coronary artery disease.
