Imaging modalties of the Aorta

Computed Tomography (CT)
  • CT is a highly accurate, rapid, reproducible, and readily available technique for detecting and sizing aortic aneurysms and for the diagnostic evaluation of suspected aortic dissection.
  • CT is also helpful at mapping branch vessels, and for detecting mimics of aortic disease (e.g. pericardial disease, gastrointestinal disease).

Magnetic Resonance (MR)
  • Imaging MR is also a highly accurate technique for aortic imaging.
  • However, the study time is lengthy and the patient is relatively inaccessible, making this modality unsuitable for acute or unstable patients.
  • MR is most often performed with intravenous gadolinium as a contrast agent, but the “black-blood” technique with spin-echo sequences can provide satisfactory images without the need for gadolinium.

  • Catheter-based aortography is an invasive technique that can demonstrate the full extent of aneurysmal disease and dissection, map branch vessel involvement, and demonstrate the presence of IAo.
  • However, aortography is not readily available in most settings, requires an expert physician operator, and requires that potentially unstable patients undergo a prolonged procedure.
