Acute Aortic Diseases: Evaluation with Computed Tomography and Magnetic Resonance Imaging

  • Chapter
  • First Online:
Emergency Chest Radiology

Abstract

Computed tomography (CT) is the first-line imaging modality for evaluation of acute aortic diseases and magnetic resonance imaging (MRI) can be used without exposure to radiation or contrast injection in selected cases of acute aortic diseases. Electrocardiography (ECG)-gated CT scanning is recommended to avoid pulsating artifacts in the ascending aorta. CT findings can be used to predict prognoses of patients with uncomplicated acute type B classic dissection or intramural hematoma. Imaging findings of an infected aortic pseudoaneurysm, traumatic pseudoaneurysm, rupturing aortic aneurysm, aortoesophageal fistula, aortobronchial fistula, noninfectious aortitis, and periaortic sclerotic disease are also discussed in this review.
