II. Standard Abdominal CT
- Indications
- Suboptimal Ultrasound of AAA
- Suspected hemodynamically stable ruptured AAA
- Advantages over Ultrasound
- Reproducible results without operator variation
- Defines surrounding periaortic anatomy
- Limitations
- Does not define periaortic Vascular Anatomy
III. Helical CT (Spiral CT) or CT Angiography
- Indications
- Preoperative AAA evaluation
- Advantages
- Defines periaortic Vascular Anatomy
- Replaces Abdominal Aortography in most cases
- Noninvasive detailed vascular imaging
- Offers three dimensional reconstruction (CTA)
