Computed tomography of the thorax1

Author and Disclosure Information


This article reviews the impact of computed tomography (CT) on the recognition and diagnosis of diseases of the thorax. Topics discussed include the chest wall, pleura, and fissures; chest trauma; mediastinal masses; the thoracic aorta; other vascular applications; metastatic disease; solitary pulmonary nodules; interventional techniques; and bronchogenic carcinoma. CT can greatly enhance the ability of the radiologist to identify disease, define its extent, and, in some cases, aid in the guidance of an interventional procedure. The major advantages of the modality are related to the axial anatomic display and its superior density discrimination capabilities.
