Figure 8c. (a) Axial contrast-enhanced CT scan shows an outward bulge (arrow) along the expected location of the left aortic sinus. This finding should not be misinterpreted as an aneurysm in a sinus of Valsalva. (b) Coronal reformatted image from CT data better demonstrates the aortic anatomy. Note that the aortic valve plane (dashed line) is oriented oblique to the axial plane. (c) Oblique axial reformatted image of the aortic valve from CT data shows the normal appearance of the aortic sinuses (arrow).
