[Spiral computed tomography with functional tests in diagnosis of chronic obstructive diseases of the lungs].

The potential of spiral computed tomography (SCT) and high resolution computed tomography (HRST) in diagnosis of chronic obstructive pulmonary diseases (COPD) is described. Semiotic sings of bronchial asthma (BA) and chronic obstructive bronchitis (COB) are specified. Informative value of SCT in differential diagnosis of BA and COB including early stage of the diseases is analysed. An updated technique of SCT and HRCT of the lungs in COPD patients is presented.
