CT
Computed tomography is the most effective method for indicating the aneurysms maximum diameter and monitoring the diameter over long periods of time.
- CT scans can accurately evaluate the thoracic aorta to determine the location and extent of the aneurysm, and the relationships with the surrounding blood vessels and organs.
Characteristic findings include:
- Increase in aortic diameter
- Shift of calcification on the aortic wall
CT scans can efficiently assess:
- A dissection
- Size of aneurysm
- Mural thrombus
- Intramural hematoma
- A rupture (free and/or contained with a hematoma)
