Three-dimensional CT of thoracic outlet syndrome: report of three cases.

Recently, three-dimensional (3-D) imaging has become useful for the diagnosis and treatment of several diseases as computed tomography (CT) imaging technology has advanced. We used three dimensional CT for determination of the narrowing of the thoracic outlet (TO) in three patients with thoracic outlet syndrome (TOS). 3D-CT images are effective for visually identifying the relationships of the structures and planning the operation in TOS.
