What anatomical structures are well seen with CT  


Structures in the chest are also well seen with CT, including bones, blood vessels, lungs, trachea, esophagus, fat, as well as the muscles of the body wall.

Compare what soft tissues structures look like on the above chest radiograph on the left and the chest CT image on the right. The trachea is seen on the radiograph, since it is air filled and more lucent than the adjacent structures of the mediastinum. Note that the esophagus, blood vessels and muscles cannot be differentiated on the radiograph, but they are easily seen on the CT.
