Overview

Although CT scanning provides detailed anatomic information and is valuable in planning abdominal aortic aneurysm repair, it is not used as a screening tool because of the potential nephrotoxicity associated with the dye load, the cost, and the exposure to radiation.

Limitations of CT Scanning

  • The limitations include:[1]
    • Potential nephrotoxicity associated with the dye load
    • Cost
    • Exposure to radiation
    • Suboptimal visualization of the origins of the aortic branch vessels
    • Occasionally, inaccurate localization of the aneurysmal neck
