High-resolution computed tomography of obstructive lung disease. 1994

Department of Radiology, University of California, San Francisco.

High-resolution CT (HRCT) scanning and dynamic CT techniques have significantly improved our ability to image morphologic abnormalities associated with chronic airflow obstruction. Abnormalities visible on HRCT include emphysema, lung cysts, and large airways abnormalities, such as bronchiectasis, which are accurately assessed using this technique. Also visible are small airways abnormalities, such as bronchiolar dilation and filling of bronchioles with mucus or fluid. Perfusion abnormalities resulting from abnormal lung ventilation result in regional differences in lung attenuation, so-called mosaic perfusion. Expiratory HRCT scans or dynamic scans during expiration can show areas of air trapping.

D011656 Pulmonary Emphysema Enlargement of air spaces distal to the TERMINAL BRONCHIOLES where gas-exchange normally takes place. This is usually due to destruction of the alveolar wall. Pulmonary emphysema can be classified by the location and distribution of the lesions.

D001989 Bronchiolitis Obliterans Inflammation of the BRONCHIOLES leading to an obstructive lung disease. Bronchioles are characterized by fibrous granulation tissue with bronchial exudates in the lumens. Clinical features include a nonproductive cough and DYSPNEA.

D001991 Bronchitis Inflammation of the large airways in the lung including any part of the BRONCHI, from the PRIMARY BRONCHI to the TERTIARY BRONCHI. Bronchitides
D003550 Cystic Fibrosis An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.

D006646 Histiocytosis, Langerhans-Cell A group of disorders resulting from the abnormal proliferation of and tissue infiltration by LANGERHANS CELLS which can be detected by their characteristic Birbeck granules (X bodies), or by monoclonal antibody staining for their surface CD1 ANTIGENS. Langerhans-cell granulomatosis can involve a single organ, or can be a systemic disorder.
