CT is a highly [...], 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.
Aortography
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.
