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
