Aortic dissection on noninvasive imaging

Representative transesophageal echocardiograms (TEE) (panels A and B) and computed tomograms (CT) (panels C and D) of a section of the descending aorta in distal aortic dissection. Panels A and C are acute studies, while B and D are from follow-up evaluation. Both TEE and CT scan show persistence of the intimal flap forming the true lumen (TL) and a markedly dilated false lumen (FL) with the development of thrombi.
