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

Figure 3 Axial contrast enhanced magnetic resonance aortogram of the same patient as in Figure 2 with type B aortic dissection. In the arterial phase image (A: Axial; B: Coronal 3D reconstruction; 30 s post injection) the true lumen is of small calibre and shows early intense contrast enhancement compared to the larger false lumen. In the second delayed phase (70 s post injection) the enhancement between the lumens becomes more similar (C: Axial; D: Coronal 3D reconstruction).
