Fig. 1. Densities in dependent lung regions observed using computed tomography (CT) and transesophageal echocardiography (TEE). In the figure, the structures were explained and the density area was outlined. This section was obtained at the mid esophageal position. Arrows show the direction of view. AO = ascending aorta; CW = chest wall; DA = descending aorta; DE = density; ES = esophagus; LA = left atrium; LV = left ventricle; PE = pleural effusion.
