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:

  • 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[1]
