RT Journal Article SR Electronic T1 CT imaging for acute aortic syndrome JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 7 OP 24 VO 75 IS 1 A1 Smith, Andrew D. A1 Schoenhagen, Paul YR 2008 UL http://www.ccjm.org/content/75/1/7.abstract AB Acute aortic syndrome can be due to acute aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer, or unstable thoracic aneurysm. These life-threatening conditions are clinically indistinguishable, often presenting with acute chest pain. Contrast-enhanced, cardiac-gated multidetector computed tomography (CT) is a highly accurate imaging method for determining the cause of acute aortic syndrome.
