Multi-detector computed tomography in the diagnosis and management of acute aortic syndromes

Figure 2 A 47-year-old gentleman with Stanford type B aortic dissection. The dissection flap is flat in all the computed tomography angiographic images. The ascending aorta is not involved and the true lumen is smaller in calibre and shows early and more intense enhancement than the false lumen at the level of the right pulmonary artery (A). The small calibre true lumen gives rise to the coeliac axis (B) and is outlined by atherosclerotic calcifications (C).
