Imaging comparison for thoracic aortic aneurysm and dissection[1,2]

Imaging comparison for thoracic aortic aneurysm and dissection[1,2]
Advantages Disadvantages
Multidetector CT angiography
Rapid image acquisition, 3D reconstruction, near-universal availability, rapid interpretation Need for iodinated contrast, radiation exposure, overestimation of aortic diameter if slices are not perpendicular to flow, image artifact at aortic root
MR angiography
No radiation, 3D reconstruction, serial imaging Limited availability, need to hold breath, time consuming, contraindicated in hemodynamically unstable patients, caution in patients with renal failure
TEE
No radiation, no iodinated contrast, can be performed at the bedside Does not image the entire aorta, semi-invasive, requires sedation and airway management
TTE
No sedation needed, no radiation, no iodinated contrast, can be performed at the bedside Does not image the entire aorta, artifact from overlying ribs
CT: computed tomography; 3D: three-dimensional; MR: magnetic resonance; TEE: transesophageal echocardiography; TTE: transthoracic echocardiography.
