Figure 1 and Figure 2 show MRAs of the normal smooth appearance of the large blood vessel (aorta) that carries blood from the heart. Figure 3 shows an MRA of a narrowed and abnormal aorta from the buildup of calcium and fat (cholesterol) in the inner lining of the artery, often called hardening of the arteries (atherosclerosis).
