Landmarks identified on contrast-enhanced cardiovascular magnetic resonance angiogram (CE-CMRA) aortic images used to divide the aorta in 5 different segments: ascending aorta (AAo)—from the valve to brachiocephalic trunk, arch—from brachiocephalic trunk to the point 20 mm distal from the left subclavian artery, descending aorta (DAo)—from the distal end of the arch to midway between the end of the arch and the renal arteries, suprarenal abdominal aorta (SAA)—from the distal end of DAo to renal arteries, infrarenal abdominal aorta (IAA)—from the renal arteries to the iliac bifurcation
