Abdominal aortic vessel wall imaging has been interested and used for studying pathological vasculature. In this study, compressed sensing (CS) 3D SPACE DANTE technique is proposed for imaging abdominal aortic aneurysm (AAA) vessel wall to accelerate imaging acquisition. Its scan/reconstruction parameters were optimized on normal volunteers then, used for patient scan. DANTE provided sufficiently dark blood signal at a large vessel like the aorta, which is essential to delineate the vessel wall. CS SPACE DANTE provided comparable image quality and vessel wall-lumen signal contrast as compared to non-accelerated SPACE DANTE technique.
