During 2002–2004 years high resolution CT had been performing to 136 patients (101 man and 35 women) at the age from 16 till 84 years (on the average 50,5 ± 2,3 years), suffering from chronic obstructive disease. Duration of the disease ranged from 2 till 28 years (on the average 13,6 ± 6,7 years). In dependence on a degree of the obstructive disorders, four group of patients were distinguished, first of which made patients without any signs of obstructive disorders (n = 41), others – patients having the first (n = 26), the second (n = 25) and the third (n = 44) degree of airway obstruction. The mean attenuation coefficient was calculated in each group of the patients. In both lungs it varied from 29,6 up to 112,0 Hu. The mean attenuation coefficient was compared to a degree of airways obstruction. Comparing the results of pneumometry with high resolution CT, we came to the conclusion, that the highest sensitivity in diagnostics of obstructive disorders can be achieved, using both the data of pneumometry and the parameters of functional high resolution CT (due to a sign of lobular “traps” on an expiration). Having assumed for the etalon of the sensitivity (100 %) the given combination of the methods, we revealed, that sensitivity of the pneumometry alone in diagnostics of airways obstruction came to 86,4% that was significantly lower (p less 0,0001). Thus, taking into account the abilities of high resolution CT and the functional pneumometry, a combined application of these two methods is expected to improve the evaluation of functional and morphological state of the lungs at chronic obstructive airways diseases.
