Overview
Computed tomography is the most effective method for measuring and monitoring the maximum outer diameter of a thoracic aortic aneurysm over long periods of time.
CT
Computed tomography 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
Computed tomography can be used to assess:
- For the presence of a dissection
- Size of aneurysm
- Mural thrombus
- Intramural hematoma
- A rupture (free and/or contained with a hematoma)

Determining the Presence and Measuring the Progression of Thoracic Aortic Disease (DO NOT EDIT)[1]
| Class I |
| "1. For measurements taken by computed tomographic imaging or magnetic resonance imaging, the external diameter should be measured perpendicular to the axis of blood flow. For aortic root measurements, the widest diameter, typically at the mid-sinus level, should be used. (Level of Evidence: C)" |
| "2. The finding of aortic dissection, aneurysm, traumatic injury and/or aortic rupture should be immediately communicated to the referring physician. (Level of Evidence:C)" |
| "3. Techniques to minimize episodic and cumulative radiation exposure should be utilized whenever possible. (Level of Evidence:)" |
