Fig. 2

Coronal images of the aortic root and ascending aorta for seven representative patients. Proposed (iNAV) and conventional (dNAV) non-contrast enhanced CMRA are showed in the first and second row respectively. Remaining respiratory motion artefacts are less noticeable with the proposed approach (blue boxes). Signal homogeneity in the blood pool is significantly improved with the proposed approach in the aortic root and ascending aorta (purple boxes) and left ventricle (yellow boxes)
