The contours of the left and right diaphragm should be visible. The right diaphragm should be visible all the way to the anterior chest wall (red arrow). Actually we see the interface between the air in the lungs and the soft tissue structures in the abdomen. The left diaphragm can only be seen to a point where it borders the heart (blue arrow). Here the interface is lost, since the heart has the same density as the structures below the diaphragm. #Clinical #Anatomy #Radiology #CXR #Lateral #Hemidiaphragm #RadiologyAssistant
