1. A method of imaging an abdominal aortic aneurysm in a subject, comprising: administering magnetic resonance contrast agent to the subject; then obtaining coronal 3D spoiled gradient echo imaging data from a coronal volume centered on the subject's abdominal aorta, wherein: the coronal volume is positioned with: a top edge at the subject's diaphragm just below the subject's heart; and a front edge anterior to: the subject's pre-aortic left renal vein where it passes under the subject's superior mesenteric artery; and the subject's common femoral arteries at the level of the subject's femoral heads; such that an anterior margin of the aneurysm is excluded from the coronal volume; and imaging data which is representative of a center of k-space is obtained when a concentration of the contrast agent in the abdominal aorta is substantially higher than a concentration of the contrast agent in veins adjacent to the aorta.
