3D non-enhanced coronary MRA combined with wall imaging in the diagnosis of coronary artery stenosis

Motivation: Advancements in coronary MR angiography (CMRA) have optimized the visualization of coronary anatomical structures, subsequently enhancing coronary artery stenosis, dilation, and certain anatomical variations【1-3】.Current meta-analysis shows that coronary MRA has a 79% accuracy rate for detecting obstructive CAD compared with gold-standard ICAGoal(s): Thus,the combining wall imaging may potentially enhances the diagnosis performance of coronary artery stenosisApproach: compare diagnostic performance of 3D -non enheanced CMRA with combined wall imagingResults: Our study suggest that combining these two techniques may improve the accuracy of coronary stenosis. Impact: CMRA has unique diagnostic in detecting coronary artery stenosis, and the improvement of diagnostic accuracywill further promote its clinical application.
