In addition to the CT angiogram, MR angiogram is sometimes used in the abdomen to detect enlargement of the abdominal aorta, known as abdominal aortic aneurysm, or aortic dissection, which is caused by a tear in the wall of the aorta. MRA can also detect narrowing or blockage of the major arteries in the abdomen. In patients experiencing abdominal pain, especially after eating, MRA can detect narrowing or blockage in the arteries supplying the intestines. Similarly, in patients with unexplained high blood pressure, particularly younger patients, MRA can detect narrowing or blockage of the arteries supplying the kidneys.
