Acute aortic syndromes (AAS) is one of the most frequently symptoms with acute chest pain. Aortic computed tomography angiography can assess aortic dissection, penetrating aortic ulcer, and intramural hematoma effectively. Imaging features include false and true lumen of aorta in aortic dissection. False lumen is usually larger than true lumen. Imaging features of intramural hematoma include thickened wall which is more than 5 mm, the thickened wall is not enhanced after injection of contrast agent. Imaging features of penetrating aortic ulcer include niche from the aortic wall. Post-processing methods include multi-planar reconstruction (MPR), curved-planar reconstruction (CPR) and volume rendering (VR). These methods are common techniques to assess acute aortic syndromes.
