Fig. 11From: Clinical applications of cardiac CT angiographyType A dissection of the ascending aorta with extension into the aortic root. a Oblique MIP demonstrates a dissection flap in the ascending aorta (black arrowheads). The dissection extends down to the right coronary artery (white arrow). A metallic stent is present in the proximal right coronary artery, obscuring the underlying vessel. b Oblique MIP again demonstrates a dissection flap in the ascending aorta (black arrowheads). The communication between the true lumen and false lumen is visualized as a defect in the dissection flap (black arrow). The proximal right coronary artery is again visualized (white arrow)Back to article page
