CT and MRI in the Evaluation of Thoracic Aortic Diseases
Figure 12
Type A dissection—(a) axial postcontrast CT scan in a 56-year-old male shows a dissection flap that involves the ascending aorta and descending thoracic aorta. (b) Sagittal reconstructed post contrast CT image shows the complete dissection flap, beginning from the aortic root and extending across the arch into the descending thoracic aorta. (c) Axial CT scan in another patient shows a Type A dissection flap in the aortic root that is extending into the left coronary artery, which is dilated.
