Imaging studies for aortic aneurysm

Imaging studyAdvantagesDisadvantages
Cardiac-gated multidetector computed tomographic angiographyHighly specific and sensitive Can diagnose vascular anomalies, tortuosityLarge doses of ionizing radiation and contrast
Magnetic resonance angiographyHighly specific and sensitive Can be accurate without using contrast Ability to assess valve diseaseProlonged scanning time Difficult for those with claustrophobia
Transthoracic echocardiographyNoninvasive, readily available Can assess valve diseaseLimited visualization of ascending aorta Accuracy reduced with “oblique” measurements
Transesophageal echocardiographyHighly specific and sensitive Ability to assess valve diseaseRequires skilled personnel Invasive, requires procedural sedation
AngiographyHighly sensitive and specificInvasive Requires contrast
