3-Dimensional DANTE-prepared sequence with non-rigid motion-correction for high-resolution dark-blood aortic imaging

Dark-blood imaging is an important tool for vascular imaging in cardiovascular disease. A novel free-breathing water/fat DANTE-prepared sequence is introduced for 3D dark-blood imaging of the thoracic and abdominal aorta. The framework integrates image navigation to enable translational and non-rigid motion correction resulting in a predictable scan time along with dual-echo Dixon gradient-echo readout for robust fat suppression. Results from healthy subjects and patients demonstrate the feasibility of the sequence for high-resolution, aortic imaging in ~7-minute acquisition time.
