title: High-resolution CT of the lungs.
abstract: High-resolution computed tomography (CT) of the lung provides detailed visualization of the lung parenchyma. The technique involves the use of thin-section axial tomography. High-resolution CT can facilitate the diagnosis of certain pulmonary processes. It is useful in differentiating similar patterns of abnormalities seen on chest radiographs, such as those seen in lymphangitic carcinomatosis and sarcoidosis, and in delineating the extent of co-morbid lung diseases, such as emphysema and asbestosis. In some chronic processes such as idiopathic pulmonary fibrosis, high-resolution CT can be used for biopsy of areas of active inflammation, thus increasing the diagnostic yield. As clinicians and radiologists become more familiar with high-resolution CT, it is likely that its role in the diagnosis and assessment of lung disease will increase.
