Contrast CT
- Provides detailed anatomic information and is valuable in planning AAA repair
- The disadvantages include:
- Nephrotoxicity
- Cost
- Exposure to radiation
- Suboptimal visualization of the origins of the aortic branch vessels
- Occasionally, inaccurate localizing of the aneurysmal neck

This patient presented with acute abdominal pain and hypotension. His non-contrast CT shows a large AAA and extensive periaortic haematoma. A thick (but subtle) hyperdense crescent is present within the aortic wall posteriorly and laterally which represents acute intramural hematoma, a sign of acute or impending rupture.
