Angiography is an imaging technique that may be used to evaluate the aorta. Dye is injected into the aorta, and an x-ray is used to show the flow of dye through the aorta. In someone with an abdominal aortic aneurysm, the dye shows an outline of an enlarged aorta.

Examples:

• Angiogram
• Aortography
• Renal arteriogram
• Aortogram showing thoracic dissection
