title: Computed tomography in interstitial lung disease.
abstract: The number and scope of published articles dealing with computed tomography of interstitial lung disease are limited. We present seven cases in which computed tomography detected the presence or extent of interstitial lung disease better than conventional radiography: two patients with histiocytosis X, one with bronchopulmonary dysplasia, one with bleomycin lung toxicity, and three with radiation-induced lung injury. The computed tomography appearance of histiocytosis X and bronchopulmonary dysplasia have not been previously described. Transverse computed tomography images provide information regarding stage of activity and nature of interstitial lung processes not available with standard imaging techniques. We advocate the use of computed tomography in the initial investigation and follow-up of patients with histiocytosis X. Post-radiation pneumonitis and fibrosis can be detected earlier with computed tomography as well.
