Dissection of the Ascending Thoracic Aorta (Images in Clinical Medicine, N Engl J Med 1994:330;1361) . The title of the Image in Clinical Medicine should have been “Dissection of the Descending Thoracic Aorta,” and the legend should have read as follows:

A dissecting aneurysm of the descending segment of the thoracic aorta was diagnosed by two-dimensional transesophageal echocardiography. The horizontal imaging plane is just distal to the aortic arch and shows a separation of the true lumen (TL) and the false lumen (FL) of the dissecting aneurysm. A color-coded flow signal in blue identifies flow away from the aortic valve in the true lumen. An echogenic crescent-shaped thrombus (Thr) almost completely fills the false lumen and leaves only a narrow unobstructed mural rim. Two images, taken at slightly different gray-scale gain settings, are shown side by side; the lower setting in the image on the left allows better visualization of the color-coded flow signal. Blue denotes flow away from and red or yellow flow toward the transducer.
