[Imaging of acquired pathologies of the thoracic aorta].

For many years, imaging of thoracic aorta has been dominated by angiography. Development of new imaging modalities has modified the diagnostic approach to thoracic aortic pathology. The knowledge of the advantages and limitations of each technique enables a better choice for patient evaluation, in particular under emergency conditions. This study is based on a review of the literature and reports the authors' experience.
