both modalities can provide a reconstructed, surface-shaded 3D display of the aorta, which is helpful in demonstrating
the anatomic relations of the aorta and its branch vessels. In contrast, TEE is not generally preferred for routine aortic imaging, because it is semiinvasive, is relatively unpleasant for the patient, does not provide full visualization of the arch vessels, and does not permit easy identification of landmarks when comparing serial examinations to assess aortic changes over time.
