Diagnosis of abdominal aortic aneurysms.
An abdominal aortic aneurysm can often be diagnosed on the basis of physical examination alone. Radiographic demonstration of calcification outlining the aneurysmal wall is the simplest way to confirm the diagnosis but is feasible in only about 50 percent of cases. Aortography carries a potential risk and often gives false-negative results. Ultrasonography and CT scanning are the safest and most reliable methods used in screening for abdominal aortic aneurysms.
