Cardiovascular Magnetic Resonance Angiography is established for serial monitoring of thoracic aortic disease. Limitations of the current approach include the diaphragmatic navigation, leading to long acquisition times and the correction of the aortic motion, solely in one direction. We propose a T2-prep bSSFP sequence that incorporates image-based navigation and inline non-rigid motion-correction for efficient, free-breathing and isotropic aortic imaging. Comparison between the conventional and the research sequence shows similar diagnostic confidence with both techniques in much shorter acquisition time [3.11.1min (iNAV) versus 11.5 min3.4 (dNAV),P<0.0001] and good agreement of aortic measurements between both techniques, holding promise for forthcoming clinical adoption.
