Fig 1 A and B, Postprocessing of aortic computed tomography angiography image by 3-dimensional volume rendering gives a good morphologic overview of the true and false lumen. C and D, Centerline analysis allows the depiction of the primary entry, located approximately 1.5 cm distal to the left subclavian artery.

Fig 2 Streamline visualization shows (A) parasagittal view of blood flow in the true and false lumen and (B) a double-oblique view of blood flow in the false lumen distal to the primary entry (color-coding according to absolute local velocity in cm/s).
