Characterization of Aortic Dissection: What the Radiologist Needs to Know

Research output: Contribution to journalReview articlepeer-review


Evaluation of acute aortic dissection by computed tomography angiography provides detailed characterization of this disease beyond the Stanford classification. Recent publications based on large patient registries and other sources have identified morphological characteristics that impact patient prognosis, and advanced understanding of both the incidence and demographics of this disease. This article reviews the recent literature and discusses the importance of imaging findings, such as aortic/false lumen diameter, signs of organ malperfusion, false lumen thrombosis, and characterization of intimal tears. The associated entity acute intramural hematoma is discussed, as well as imaging features that predict adverse outcomes. Familiarity with these imaging characteristics maximizes the utility of radiographic evaluation in this disease.
