Three-dimensional (3D) black-blood MRI is a promising noninvasive imaging technique for assessing aortic atherosclerotic plaque. In this work, a low rank patch-based technique is proposed, and combined with a 3D modulated vFA-FSE sequence for high-resolution thoracic aorta imaging. The comparison was conducted on healthy volunteers and compared against a conventional GRAPPA acquisition to assess the feasibility of the proposed scheme. The results showed the reconstruction scheme was able to visualize the lumen areas clearly and improve the vessel sharpness and contrast ratio significantly.
