The Role of CTA, MRA, and Sonography in Aortic Dissection

Abstract

Aortic dissection is an emergent condition requiring rapid diagnosis and immediate treatment. Patients with aortic dissection typically present with complaints of a sudden onset of severe abdominal and back pain. Patients with a suspected dissection may undergo a variety of imaging tests such as computed tomography angiography, sonography, and/or magnetic resonance angiography. The role of these diagnostic imaging modalities for aortic dissection is examined in detail in this literature review. These imaging modalities are compared and contrasted by reviewing their advantages, disadvantages, and overall effectiveness for aortic dissection.
