Multislice CT virtual intravascular endoscopy of aortic dissection: A pictorial essay

Figure 5 Stanford type A dissection with the dissection originating at the aortic root. The intimal flap is clearly displayed on 2D axial and coronal reformatted images (long arrows in A and B) with the left coronary artery arising from the true lumen (T) (arrowhead). Virtual intravascular endoscopy shows the intimal tear which is located at the aortic root (arrow in C) proximal to the left ventricle. Both of the coronary ostia arise from the true lumen with the intimal flap extending to the left coronary ostium (D, E). Short arrows in A and B indicate the cobweb sign in the false lumen (F).
